Really, though, acting as examples, and ideally convincing others to view money and obligation similarly to us, is about the most effective thing we can do. If we work hard to reduce our food spending from $200/month to $150/month, that has roughly 12% of the effect of someone who earns $50K going from donating roughly nothing to ten percent. So, if you don't currently donate a substantial fraction of your income, I'd be happy to talk to you about why I think it's the right thing to do.
