There is an old adage that says you'll be happy and successful if you "do what you love" for a living.  Don't believe what you hear.  That saying is only almost right.  "Love what you do for a living" is better advice, and the difference is not mere subtlety.  We should hold the things we truly love as intimate and not fully invest them in the pursuit of trade or commerce.  On the other hand, the things we do professionally must have some underlying passion if we are going to be successful.
