Happiness doesn't come from money and material things, but from the self-expression they can offer you.
Once I was in the Blink-182, going to Iraq was really touching. It was kind of emo for me, going and meeting soldiers who were, like, 19 and hadn't even met their kids. . . Or dealing with depression. Just being with those soldiers and traveling with them in helicopters and people with M-16s. It was an eye-opener.
