I try to put things into two buckets: one I can do something about and one I can’t. The things I can’t do anything about, I try to ignore. There’s no use, for example, being jealous of other people’s success or good luck; it won’t make me any happier. Nor is there any upside in worrying about a bad situation in which I find myself. There is, however, a lot to be gained from considering how I can move to a better place.
