"When most people practice, they focus on the things that they can do effortless. Expert practice is different. It entails considerable, specific and sustained efforts to do something you can't do well, or even at all. It is only by working on what you can't do that you turn into the expert you want to become."

"Deliberate practice is not mechanically repeating tasks that come easily, but rather targeting and attacking specific areas that need improvement."

"Extended deliberate practice is the true key to success"
