What are you tracking in your life? Numbers matter — you cannot manage what you cannot measure — but the moment a measure becomes the target, it stops measuring anything. In this episode: Goodhart’s Law, the famous cautionary tales of metrics gamed into uselessness, and why after 30 years and 600,000 people live I can tell you almost nobody tracks what actually matters. The audit: for every number you chase, ask what it’s for — and find your giant nail.

Speaker:

The moment you started tracking it, it started lying

Speaker:

to you Well, hello my friend.

Speaker:

This is the Daily Podcast.

Speaker:

My name's Jonathan Doyle.

Speaker:

I wanna ask you a question.

Speaker:

What are you tracking in your life?

Speaker:

Let's talk a little bit about numbers.

Speaker:

One of the key things to genuine personal growth, personal development, leadership,

Speaker:

growing businesses, growing anything that's significant to you, is getting

Speaker:

really, really good at the numbers.

Speaker:

It's that old saying, "You cannot manage what you cannot measure." So I wanna

Speaker:

introduce a little sort of paradox here that numbers are really important if

Speaker:

you wanna grow, but simultaneously, if the numbers become the thing themselves,

Speaker:

they can really lead you off track.

Speaker:

Does that sound a little cryptic?

Speaker:

So let me clear this up a little bit.

Speaker:

First thing, numbers matter.

Speaker:

My day is run by a whole bunch of significant numbers, but the central

Speaker:

thesis that I wanna introduce in this short message is that the purpose

Speaker:

of the numbers is the crucial thing.

Speaker:

The numbers that you measure in your life are not the point in

Speaker:

themselves, it's where those numbers are designed to be taking you.

Speaker:

So it might be weight, it might be, uh, time spent with

Speaker:

family, it might be nutrition.

Speaker:

There's a whole number of things we can definitely manage and measure, but

Speaker:

the problem becomes if we lock into the numbers purely and we lose track of

Speaker:

where they're supposed to be taking us.

Speaker:

I wanna give you some examples from history of how this plays out.

Speaker:

And before we get there, I just, I guess the way I started this, I wanna ask

Speaker:

you, are you, what are you tracking?

Speaker:

Because I can promise you, after more than 30 years speaking to

Speaker:

more than 600,000 people around the world in live events and many, many

Speaker:

conversations afterwards, that so few people are really tracking anything.

Speaker:

And I think to a degree it is true that you can't really manage and

Speaker:

change what's not even being measured, because how do you know if there's

Speaker:

been a significant movement either way?

Speaker:

So I really wanna put that idea in your head.

Speaker:

Numbers do matter.

Speaker:

If you wanna grow, if there's some area of your life that you do want

Speaker:

to improve, you've gotta start paying attention to the numbers.

Speaker:

But in this paradoxical episode, you don't want the numbers

Speaker:

themselves to be the pure thing.

Speaker:

Why?

Speaker:

Let's get back to history.

Speaker:

We're gonna talk about something called the Goodhart Law, or Goodhart's Law.

Speaker:

This is from the economist, a British economist called Charles Goodhart, and he

Speaker:

figured out that in every organization and for every self-improver, they eventually

Speaker:

discover that when a measure becomes a target, it ceases to be a good measure.

Speaker:

Hear that again.

Speaker:

When the measure becomes a target itself, it's no longer useful as a measure.

Speaker:

So Goodhart gives an interesting example, uh, example from Soviet-era Russia.

Speaker:

Now, I don't know if you know this, but they used to have these five-year plans,

Speaker:

centralized control of the economy.

Speaker:

They'd send out these plans, and every factory would be regulated

Speaker:

and had to produce a certain number of whatever the X was, whatever

Speaker:

they were supposed to be producing.

Speaker:

And the example, the famous example from Goodhart was Soviet nail

Speaker:

factories So they were sent an order that they were to be judged by

Speaker:

the weight of nails they produced.

Speaker:

So they might say, you have to produce 50 kilos of nails by the end of the

Speaker:

month, or 100 kilos of nails, or 10 tons of nails, whatever the number was.

Speaker:

The people in the factory figured out that what you could do was just produce

Speaker:

a small number of very, very large nails.

Speaker:

Like you produce a 10-kilo nail, you can still say, "Hey, we hit the

Speaker:

100-ton target," but it just turns out that they're all made up of 10-kilo

Speaker:

nails that absolutely nobody can use.

Speaker:

So, and on the other side of this, this gets even more amusing, that if the, if

Speaker:

the factory was sent an order from Russian central economic control that they had

Speaker:

to produce a certain volume of nails, so you must produce 10,000 nails a month.

Speaker:

They just started producing tiny little nails that were utterly useless.

Speaker:

So you can see in that era that the minute they made the actual

Speaker:

measure the thing, it basically broke down in any way as being useful.

Speaker:

So are you with me?

Speaker:

Yeah, I don't wanna be, I don't wanna lose you here, but basically once you-- as soon

Speaker:

as you say, "Hey, the number is the thing.

Speaker:

The only thing that matters is the number, not what the number's supposed

Speaker:

to actually create, just the number," the whole thing tends to get a bit weird.

Speaker:

And the other great example, which was actually 100 years before Charles

Speaker:

Goodhart, was when the British had, still had colonial rule over India,

Speaker:

and the capital, Delhi, had huge problems with cobras, of all things.

Speaker:

So they put out a, an edict that they would pay for dead cobras.

Speaker:

So sure enough, cobras start to come in, very dead.

Speaker:

But the locals realized that if you bred cobras, you could start getting paid.

Speaker:

So people started breeding more and more cobras so they could hand

Speaker:

go and kill them and hand them in.

Speaker:

And then, of course, they figured out this was a problem, so they immediately

Speaker:

dropped the whole thing, and all of a sudden, lots of people had large numbers

Speaker:

of cobras that they could no longer sell, so they just released them on the…

Speaker:

I don't know if you're finding this funny.

Speaker:

I'm really enjoying myself in the studio.

Speaker:

So the measure, which was dead cobras, rather than helping with

Speaker:

the problem, as soon as it became the fixation point, it actually

Speaker:

created a much, much bigger problem.

Speaker:

So the message in both of these is that numbers, if they're pursued

Speaker:

purely for themselves, can eventually become less than useful to us.

Speaker:

So I remember when I was cycling a great deal, I, I, you know, I still do a huge

Speaker:

amount of fitness, as many of you know.

Speaker:

But for a long time, I was cycling at a very high level, and there's,

Speaker:

there was a kind of mystical goal in the cycling community.

Speaker:

It was, which was a 500K week.

Speaker:

You know, if you did 300Ks in a week, that was pretty standard back then for when,

Speaker:

what the kind of riding we were doing.

Speaker:

But if you did 500 kilometers in a week, people would notice on Strava, right?

Speaker:

They'd see your, your metrics on the Strava app and be

Speaker:

like, "Wow, it's a 500K week.

Speaker:

You know, it's a 500K week." And you're like, "Yeah, yeah." And a few

Speaker:

times I did that, and my memories are, I think once I did a 600K week,

Speaker:

and I remember being absolutely destroyed for about the next 10 days.

Speaker:

But What I'm trying to share with you is that the magical 500-kilometer number

Speaker:

just became a thing in its own right.

Speaker:

So it wasn't about whether it was making you fitter or faster or

Speaker:

happier, it was just a magical number that magically you chased.

Speaker:

So it became, the number itself became pretty useless in the great journey

Speaker:

of health and fitness and growth.

Speaker:

So that number became something that I became a slave to, and your

Speaker:

identity gets tied up in it all, "I must do 500 this week." And then

Speaker:

you'll get people on Strava that do, you know, 10,000 kilometers a

Speaker:

year is, like, a good benchmark.

Speaker:

So people would just chase that, regardless of whether they're getting

Speaker:

short-tempered with their families 'cause they can't sleep properly,

Speaker:

'cause their cortisol's too high, 'cause they're riding too much.

Speaker:

All these things kind of flow from it.

Speaker:

So really what I wanna bring you back to today is when we look at numbers in your

Speaker:

life, they've gotta be serving you, right?

Speaker:

They've gotta be serving you.

Speaker:

So let me take you through what that looks like for me.

Speaker:

Uh, I've learned in, more recently, I'm on a very, very strict training program,

Speaker:

which I absolutely love, and it was because I was at 90 kilos when I was power

Speaker:

lifting, and I'm, you know, I'm, I'm only 5'7", 5'8", so I was really bulking out.

Speaker:

And I w- I, you know, it was muscle mostly, but I couldn't fit anything.

Speaker:

So I set a goal to go back to my bench weight, which is about 75 kilos.

Speaker:

This is a 15-kilo weight drop.

Speaker:

So I built a very targeted program, and one of the things

Speaker:

I had to do for the first time was really dial in the nutrition.

Speaker:

So I had to, uh, do, sort of design macro targets every day, so protein,

Speaker:

carbohydrates, and fats had to be at a very specific level every single day.

Speaker:

And I've got a bunch of apps that help me with it, and it was the first time in my

Speaker:

life that I had to, uh, you know, measure, uh, calorie intake by weighing everything.

Speaker:

So literally, even today, even before I came in the studio, I weigh everything.

Speaker:

I have scales.

Speaker:

I eat very carefully.

Speaker:

The results are phenomenal.

Speaker:

I've never been in better shape in my life.

Speaker:

And I, listen, I'm not telling you to do this.

Speaker:

Very clear, this is not advice.

Speaker:

I'm just telling you that what I discovered was that if you want

Speaker:

extraordinary results, you've really gotta get good on the numbers, and

Speaker:

that's exactly what I did, is I started to get really good on the numbers.

Speaker:

And I've found that they've served me immensely.

Speaker:

But could you imagine if they were just abstract numbers that

Speaker:

I was chasing for no good reason?

Speaker:

The point of these numbers is that they are taking me to a

Speaker:

place that I'm trying to get to.

Speaker:

So my purpose is to get back to 75 kilos while keeping all the

Speaker:

muscle that I got out at 90 kilos.

Speaker:

That's quite a trade.

Speaker:

You gotta work pretty hard to get that right.

Speaker:

So these numbers have a very real purpose in my life.

Speaker:

You know, we have a lot of staff now, and so when I look at ROI

Speaker:

spreadsheets and things that I have to manage in the business,

Speaker:

it's like looking really carefully.

Speaker:

Are these numbers serving me?

Speaker:

Where are these numbers supposed to be taking me?

Speaker:

So now let's talk about you.

Speaker:

Are you tracking anything?

Speaker:

And if you are tracking anything, what is the purpose of that tracking?

Speaker:

Where is it designed to take you to?

Speaker:

So numbers can be enormously useful for you.

Speaker:

You know, number of hours spent with your kids if you wanna do that.

Speaker:

Like, I, I know some people say, "That sounds crazy.

Speaker:

That sounds extreme." I say, "Well, in this world, we're so busy, there's

Speaker:

so much happening, there's so much complexity that sometimes you gotta

Speaker:

be really deliberate and say, 'How much time am I giving to these people?

Speaker:

How much time am I giving to the people that I really love and care about?'"

Speaker:

And maybe you start to track that, but again, the purpose isn't to post

Speaker:

on your social feeds, "I spent 3.7 hours with my children this week,"

Speaker:

and virtue signal to everybody.

Speaker:

The purpose is, is that time, is that metric getting you closer to what you

Speaker:

want, which is a deep relationship with your children or your friends or

Speaker:

whatever number is relevant for you.

Speaker:

So that's the essential purpose of this.

Speaker:

I really wanna put two thoughts in your mind today.

Speaker:

Are you tracking anything?

Speaker:

Are you tracking anything?

Speaker:

So all I can tell you is that for me, every day numbers are significant.

Speaker:

I play golf, you know, probably four or five days a week, and I know that

Speaker:

sounds like I have the greatest life in history, but I play with my kids

Speaker:

and it's very structured and I do a huge amount of practice 'cause

Speaker:

I love the game and I love having something that pushes me to get better.

Speaker:

And so when I'm really working hard on my handicap, I'm tracking everything.

Speaker:

I'm out there tracking greens hit in regulation.

Speaker:

I'm tracking, uh, number of putts taken.

Speaker:

I'm taking, you know, tracking number of drives on fairway, all this sort of

Speaker:

stuff, and the purpose isn't some random interest in numbers for their own sake.

Speaker:

The purpose is because I wanna get better.

Speaker:

I love the game and I love the purity of it, and I wanna keep getting better at it.

Speaker:

So what are your numbers?

Speaker:

What are you tracking?

Speaker:

Are you tracking anything?

Speaker:

If you wanna change your weight, your health, your fitness, do you wanna--

Speaker:

maybe you wanna run a marathon, maybe you wanna run a half marathon,

Speaker:

maybe you just wanna run 5K, maybe you wanna walk around the block.

Speaker:

Maybe you're recovering from an injury or an illness.

Speaker:

And so those numbers, maybe you walked 10 steps today.

Speaker:

Maybe you walked 10 steps, and then you track it, and then

Speaker:

tomorrow you walk 20 steps.

Speaker:

But again, the purpose isn't to fall asleep going, "Oh, I did 20 today."

Speaker:

The purpose is, "I'm closer to that 5K.

Speaker:

I'm closer to being that healthy, vibrant, fit person that I really wanna be."

Speaker:

So make them-- Remember I said a couple of episodes ago, Plato's

Speaker:

great servant that, uh, Plato's great quote, that our emotions are wonderful

Speaker:

servants but terrible masters?

Speaker:

I always love that quote.

Speaker:

What about the idea that numbers are excellent servants but terrible

Speaker:

masters if they run our entire life?

Speaker:

So I hope that's useful to you.

Speaker:

I hope that's a blessing to you.

Speaker:

word, jaydoylespeaks, 'cause you will see me every single day doing

Speaker:

something involving some sort of insanity, usually involving numbers.

Speaker:

God bless you, my friend.

Speaker:

You ready for the outro?

Speaker:

You ready for that one last thought to leave in your mind?

Speaker:

Here it comes.

Speaker:

Chase the thing, not the number that points at the thing.

Speaker:

The number will follow, and if it doesn't, it was the wrong number
