John Danaher was on Lex Fridman again. Here he talks about needing to accept failure and frustration as part of the process.

It’s the only way to go. Like if you, if you can’t wrap your head around the idea that trying to acquire new skills will create a temporary time where your effectiveness diminishes as you’re trying to bring on new skills, you’re never gonna make it because you always stay at whatever skill set you are.

The whole mental trick is to imbue this idea of delayed gratification, that you have to accept that when I bring on new moves, my overall effectiveness will diminish. But there’s the belief that in time as my skill performance increases, it will increase over time, but it will come at the price of initial frustration and failure.

The video version is cool because they review his team’s ADCC performance: https://www.youtube.com/watch?v=iZRbD7q1n-U
