two years ago, my life change forever. My wife Kelsey and I welcome our daughter Lela into the world.
Now, becoming parents is an amazing experience. Your whole world changes overnight. And all of your priorities change immediately. So fast that it is really difficult to process sometimes.
this was new to me. This is an actual outfit, I thought this was a good idea. And even Lela knows that it's not a good idea.
So there is so much to learn and so much craziness all at once.
and to add to the craziness, Kelsey and I both work at home, we are entrepreneurs, we run our own businesses.
So, Kelsey develops courses online for yoga teachers. I'm an author. And so I'm working from home, Kelsey is working from home. we have an infant and we are trying to make sure that everything gets done that needs done. And life is really, really busy.
And a couple of weeks into the amazing experience, when the sleep deprivation really kicked in, like around week eight, I had this thought, and it was the same thought that parents across the ages, internationally, everybody had this thought, which is I am never going to have the free time ever again.
Somebody said it' s true. It's not exactly true, But It feels really true at that moment. And this was really disconcerting to me because one of the things that I enjoy more than anything else is learning new things. Getting curious about something and diving in and fiddling around and learning through trial and error. And eventually becoming pretty good at something.
Without this free time, I didn't know how I was ever going to do that ever again, and so I'm a big geek, I want to keep learning things, I want to keep growing. And so what I've decided to do was, go to the library, and go to the bookstore, and look at what research says about how we learn and how we learn quickly. And I read a bunch of books, I read a bunch of websites. And tried to answer the question of how long does it take to acquire a new skill? Do you know what I found? 10,000 hours!
what the research says and what we expect, and have experienced, they don't match up.
The 10,000-hour rule came out of studies of expert-level performance.
And he tried to figure out how long does it take to the top of those kinds of fields. And he found is the more deliberate practice, the more time that those individuals spend practicing the elements of whatever it is they do, the more time you spend, the better you get. And the folks at the tippy top of their fields put in around 10,000 hours of practice.
and the central piece of that book was the 10,000-hour rule.
So the message, it takes 10,000 hours to reach the top of an ultra-competitive field, became, it takes 10,000 hours to become an expert at something, which became, it takes 10,000 hours to become good at something, which became it takes 10,000 hours to learn something.
But the last statement, it takes 10,000 hours to learn something.
Now researcher, whether they' re studying a motor skill, something you do physically or a mental skill, they like to study things that they can time. 'cause you can quantify that, right? '
So they' ll give research participants a little task, something that requires a physical arrangement, or something that requires learning a little mental trick, and they' ll time how long a participant takes to complete the skill. And here's what this graph says when you start, so when researchers gave the participants a task, it took them a really long time, 'cause It was new and they were horrible.' with a little bit practice, they get better an better, and the early part of practice is really, really efficient. People get good at things with just a little bit of practice.
There is a way to practice intelligently. There is a way to practice efficiently, that will make sure you invest those 20 hours in the most effective way that you possible you can.
The first is to deconstruct the skill. Design exactly what you want to be able to do when you did, and then look at the skill and break it down into smaller pieces. Most of the things that we think of as skills are actually big bundles of skill that require all sorts of different things.
The more you can break apart of skill, the more you are able to decide, what are the parts of this skill that would actually help me to get to what I want?
And then you can practice those first. and If you practice the most important things first, you will be able to improve your performance in the least amount of time possible.
So, get three to five resources about what it is you are trying to learn.
what you want to do is learn just enough.
So the learning became a way of getting better at noticing when you
are making a mistake and then doing something a little different.
