Money defines too many people.
What makes you happier? Sitting at home with all your material gifts, or being out there with people you care about, that you don't judge on wealth? Rather than play on a PS3 with 10 000 games, staring into a gigantic plasma tv, I would rather be outside doing things you don't have to pay for.
The best things in life really are free. The happier people are the people who don't care about it. After all, if you're only focused on money, where's the time for being happy? You might be content with your financial position, but with your own life, are you really?
