My wife and I talked about it. We decided to take a different tack. Instead of giving something up, we decided to sacrifice some of our time to increase our volunteering efforts for good local causes. So instead of giving up certain foods or activities or whatever, we're giving up free time.
Our reasoning was that giving up stuff really helps no one, whereas giving away some of our time does produce positive results in the community.
"Hey, for every ten dollars, that's another hour that I have to be in the work place. That's an hour of my life. And my life is a very finite thing. I have only 'x' number of hours left before I'm dead. So how do I want to use these hours of my life? Do I want to use them just spending it on more crap and more stuff, or do I want to start getting a handle on it and using my life more intelligently?" -- Joe Dominguez (1938 - 1997)
