If you’re trying to decide between two things that sound equally good, like which place to have lunch, flip a coin. When the coin picks one for you, sometimes you’ll immediately feel happy or sad about what it picked. If you notice that happening, do the thing that makes you happy instead of the thing the coin picked. (If you don’t notice that, just do what the coin picks, since either outcome is probably fine, and you won’t have to think about the decision any more.)
