But working hard isn't ever enough to reach the pinnacle of achievement. I could have worked my ass off at basketball, from age 3, and I would have never been an NBA player. Someone with more natural gifts than me, but fewer than Michael Jordan, might work hard his whole life and only brush the minor league/NBA border.
Probably, but you'd be surprised. I don't know if I would say Charles Barkley was "naturally talented" at basketball--his body type was all wrong, especially since he played in the era before everyone bulked up--but he worked his ass off and became one of the greats.
Same thing with Jim Courier in tennis. He became #1 in the world in tennis by working harder than anyone else. He didn't have half the talent or strokes of some of the other guys, but he just worked his balls off. It's the same story in just about every profession: the guys who work the hardest are the guys who climb to the top. Sure there are exceptions, but this is the general rule. Cheers, Scott
