How to become an expert at anything
"...estimated that chess experts spend up to 50,000 hours learning to play chess"
"...tested experts and beginning players with randomly placed pieces. With random positions (those which did not make sense in chess) experts were no better at memorizing board positions than beginners. With meaningful positions, the experts were much better than beginners."
"The same is true in any domain of expertise. The expert learns to recognize significant patterns and remember them easily."
