Deliberate practice is superior to all other forms of training. That is a “solved problem” in the academic field of talent development. It might as well be a law of physics.

Deliberate practice is not mindless repetition. If you’re doing the same thing over and over again, then you’re doing deliberate practice wrong.

Deliberate practice is about making performance-improving adjustments on every single repetition.

Deliberate practice requires effort and is not inherently enjoyable. Individuals are motivated to practice because practice improves performance.

This connected in my brain with a story I heard Tobi Lütke tell during one of his podcast interviews about the “Talent Code” book:

The tl;dr of why I think video games are good is because of transfer learning. […]

There was a famous story about people analyzing why Brazilians became so much better at soccer than anyone else. […]

It turns out, in Brazil there was a culture of playing a pickup game, a version of soccer that was played in a much smaller space and with fewer players. And the players did all the things you need to be good at soccer, but they did them significantly more often, because there was more ball contact per person.

Just because that’s a different game than soccer doesn’t mean people won’t learn soccer skills. They had way more ball contact than someone who went through the British system, by the time they entered the Premier league, for instance.

Basically, the Brazilians found a way to get more repetitions of deliberate practice, thus allowing them to learn faster than everybody else.

It’s true about video games, too: https://x.com/aakashgupta/status/2049397346010828881?s=46

This further connected in my brain with something else: given that deliberate practice requires effort and isn’t enjoyable, I think that being in true deliberate practice should slow down life.
