Pledge to Give
I recognise that I can use part of my income to do a significant amount of good. Since I can live well enough on a smaller income, I pledge that from December 16, 2020 until the day I retire I shall give 5% of what I earn to whichever organisations can most effectively use it to improve the lives of others, now and in the years to come. I make this pledge freely, openly, and sincerely.
