When you hear about something terrible, calm yourself by asking, If there had been an equally large positive improvement, would I have heard about that? Even if there had been hundreds of larger improvements, would I have heard? Would I ever hear about children who don’t drown? Can I see a decrease in child drownings, or in deaths from tuberculosis, out my window, or on the news, or in a charity’s publicity material? Keep in mind that the positive changes may be more common, but they don’t find you. You need to find them. (And if you look in the statistics, they are everywhere.)
