In April’s Men’s Journal Bear Grylls give this little nugget of advice (well he gives plenty, but this one in particular):

I try to give 10 percent of what I earn to friends struggling with their mortgages or somebody who needs a really good holiday. That’s a rule I’ve always followed, and it’s been really good in our lives. Money is like water: If you don’t let it flow, it’s just going to get stagnant.”

I’m all for it. You can paypal me the money. But when/if I start making some bank, I’ll definitely do this. It’s better than giving 10% to some church or whatever to build a fancier church. Maybe not a tax write-off, but not like any kind of generosity or charity should be motivated by tax benefits.
