Actually, this expertise is a rather well studied topic in cognitive psychology. If I remember correctly, people become experts after 10,000 hours of practice.

Actually, this expertise is a rather well studied topic in cognitive psychology. If I remember correctly, people become experts after 10,000 hours of practice. Additionally, there is very little variation due to talent. Most "talent" comes purely from practice. Feel free to correct me if I'm wrong, this just what I remember from lecture in my cog psych class.
