I don't know if I've mentioned it on this blog but a while ago I took the Giving What We Can pledge to donate 10% of my pre-tax income every year to efficient charities. In general I'd recommend following Givewell's recommendations fairly closely.  In past years I've strayed beyond them a bit, in particular giving a bit extra to charities that provide micronutrients in poor countries on the theory that allowing kids to grow up healthier is investing in the future and maybe I ought to prioritize that over saving as many lives as I can right now.
