By earning more money than I need to independently support myself and my lifestyle such that savings accumulate. These savings could come in handy in case of emergency or loss, or otherwise, they will be there when I get older and my ability to work is compromised. Keeping this up is not difficult for me because I don't want much materially - unless something unusual comes up, I don't use a lot of money. I love to maximize the usefulness and versatility of small things, and my interests are about as inexpensive as they get.
When was the last time you took pleasure in the misfortune of someone else, if ever?
