I guess that means what you mean by 'gifted' or 'notable'. Being very creative, having the confidence to express this creativity and most importantly, being both capable and _willing_ to have a high workload over time is probably correlated to having high IQ, but I strongly doubt that they follow in lockstep. Perseverence and hard work seems to be more correlated to "success" than IQ.

IMHO there's a lot of smart people that compromise their health and well-being by forcing themselves to work too hard at being notable, and in itself I don't think these are the best objectives to strive for in life.
