Breaking and entering for fun and profit
Do you have anything you want to do?
I would like to do Shakespeare.
I don't want to do it forever, though.
You don't have to. Try things out. If you don't like what you're doing, do something else.
How do you know when to stop?
Some people stop because they're tired of change. Others because they're happy. And some people stop because they're being paid well enough to be unhappy.
