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.
Participate joyfully in the sorrows of the world. We cannot cure the world of sorrows, but we can choose to live in joy.
What we are really living for is the experience of life, both the pain and the pleasure.
