I think I read somewhere that once your IQ is above 120 or so, you're pretty much "smart enough" for any career path, and the correlation between IQ and success begins to break down. Other factors become very important, such as drive, risk aversion, ethics, luck, etc. And of course, a sample size of two is much too small to read anything into.

Ditto what others have said. Intelligence gives you the ability to properly assess your options in light of your own individual values and circumstances.
