three things are required but only two are really needed: talent (genetics) training (determination) opportunity (luck) As Spassky loved saying Korchnoi was the hardest working most dedicated chess player ever, but had no talent, so he always just lost the world championships to Spassky, Fischer, Karpov and Kasparov. Never ever under estimate the importance of opportunity. Some have got to world championships simply because of this. Opportunity is being there on race day when the competition is not, it is having the parent which buys the better equipment, it is being given a place on a team for political reasons, ext. Never ever waste an opportunity to prove that you have either talent or training (determination). On talent read the book "the talent code" and "outliers". Often talent is the result of hard work, which was made to feel like fun, after all its not work if you enjoy it.
