Do you need to be talented or dedicated to make it good in any di scipline?

As penned by Mark Betts:
I think people can be born with natural sporting talent but this can only give you a good start in sport, one of the reasons you often hear of professionals excelling in a number of sports when young. Training methods will then take you to a top professional level.

But once at this stage i think psychological aspects play a huge role.

Oh and there's always the theory that footballers are born with an eye deficiency giving slightly wider vision allowing them to see more of their surroundings???
