Life is to be lived. If you have to support yourself, you had bloody 

well better find some way that is going to be interesting. And you 

don't do that by sitting around.

~Katherine Hepburn

So I guess that the trick is to learn how to combine the two: have fun while you are working hard at something interesting?
