I looked at my life and realized how completely great it was. We can complain about the small things (the people who have such comfortable lives) and these people don't get that luxury. Imagine that complaining can be a luxury! Sure, I don't live in a mansion with butlers and maids and have a lot of money; but why would you even spend money on something as useless as that when you can spend it to help someone else? We don't need all the things that we can have; definitely not. So whenever I look at something and say "hey, that's cool. I want it" I just think about all those people out there who need that money much more than me, and it cures my craving pretty quickly.
