Joseph Campbell - Wisdom of the Day

"I think a person who takes a job in order to live––that is to say, for the money––has turned himself into a slave. WORK begins when you don't like what you're doing. There's a wise saying: make your hobby your source of income. Then there's no such thing as work, and there's no such thing as getting tired. That's been my experience. I did just what I wanted to do. It takes a little courage at first, because who the hell wants you to do just what you want to do; they've all got a lot of plans for you. But you can make it happen. I think it's very important for a young person to have the courage to do what seems to him significant in his life, and not just take a job in order to make money. But this takes a bit of prudence and very careful planning, and may delay financial achievement and comfortable living. But the ultimate result will be very much to his pleasure."
