@Adriel: The biggest predictive factor for success and for arriving at the level most people call "talent" is referred to as the "drudge" gene. That means you can invest the time in drudge work, even though it's boring, in order to build skills.
Thats a good point. People throw around the term talent too loosely sometimes; where a lot of the times its hard, time consuming work and practice. So in reality, "Hes talented because he can do 8 hours of play and practice everyday".
