"Because if you say that getting the money is the most important thing, you will spend your life completely wasting your time. You will be doing things you don’t like doing in order to go on living that is to go on doing things you don’t like doing. Which is STUPID! Better to have a short life that is full of what you like doing than a long life spent in a miserable way.
And after all, if you do really like what you're doing, it doesn’t matter what it is, you can eventually become a master of it. It’s the only way to become a master of something, to be really with it. And then you’ll be able to get a good fee for whatever it is. So don’t worry too much. Somebody’s interested in everything. And anything you can be interested in, you’ll find others who are."
