"Bobby Fischer was a rare combination of talent and hard work"
SInce his ability can be explained by hard work alone then why do we need the lumineferous aether of talent?
Because hard work alone wont make one the best in the world at anything. Some people just have more innate ability/aptitude/TALENT than others in certain areas....
Because you say so?
You believe that a hundred people all working as hard as they can will all become exactly as good?
Find me one hundred identical people
A friend of mine is straight, totally, his brother totally gay, and the reason is not talent, one had more talent in one field!
What has that got to do with anything?
