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 own 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 lots of plans for you. But you can make it happen.
