Get rich quick off the backs of others. Try getting people to work for you for a pittance and selling the things they make for a fortune, feelings of self-hatred and worthlessness should have you miserable eventually. 

Or maybe you could just steal a load of intellectual property off the internet, sell it on as your own and watch the cashcome flooding in.

The main thing to be careful of is that you don't make any kind of concerted effort or do anything worthwhile. if you do you might end up feeling cheerful and optimistic, like you were a worthwhile human being. And we wouldn't want that to happen.
