My 11-year-old son Alex, without anyone suggesting it, donated $100 to the Against Malaria Foundation and so gave up the chance to buy 50 Hearthstone arena tickets.
As a pro Hearthstone player and effective altruist, nicely done! If your son is interested in a free lesson I'd be happy to help him improve his game as a reward for his generosity (though I haven't played arena in a while).
Remember, however, that this isn't any kind of progress thread. Nor is it any kind of proposal thread. This thread is solely for people to talk about the awesome things they have done. Not "will do." Not "are working on." Have already done. This is to cultivate an environment of object level productivity rather than meta-productivity methods. For example:
So, what's the coolest thing you've done this month?
