Almost four years ago, I pledged with Giving What We Can. Members pledge 10% of their incomes to the best charities they can find (with students and those with no income pledging 1% of their spending money).
In the time since, I've felt good about making this commitment. I like having it as part of my routine, something that I know is part of my plan in the years to come. It's a confirmation of what I value—a safe and healthy life not just for me and mine, but for all families around the world. And I've enjoyed the connections with other people who have made this choice.
I'm also a fan of mini-pledges for people who aren't sure about their long-term plan. For a year, or a month, or a semester, make a plan for how much you will donate. See what it's like. Afterwards, maybe it will feel like a good amount. Maybe you'll realize you want to cut back on giving next time. (Jeff and I did that the year we forgot about taxes when making our budget!) Or maybe you'll decide you want to ramp up to something more ambitious. In any case, you'll learn something about how you handle money, and you'll be acting intentionally instead of haphazardly. If you want, you can sign up for "Try Giving" on the Giving What We Can site.
This year I'll be giving largely to the Against Malaria Foundation.
