I think this holds true across the board. True top performers aren’t the best because they learned fancy moves or techniques-it’s because they have practiced the basics to such a high extent that performing them is completely natural. That base allows you to build and expand more into your natural repertoire. Trying to mentally overcome that ability in the moment instead of trusting that base and letting your honed instincts work usually leads to failure. We don't rise to the level of our expectations, we fall to the level of our training
"When most people think about getting better, they think about adding pieces onto themselves. What I'm saying is, think about better as the first thing you do is you have to cut off a limb. You do surgery on yourself with a pocket knife. What you're doing is you're cutting out that thing that you held as true that wasn't. You first have to eliminate that. When you do there's a vacuum, and into that vacuum you can place something that's true. Most people don't want to do that work. But if you do that work, you're forever transformed."
