Being pessimistic is typically seen as a bad trait, but it's not all bad news. The School of Life takes a look at some of pessimism's more redeeming qualities in the video above.
The big pitch here is that pessimism helps you with defining expectation. When you keep your expectations in check, you won't expect anyone to hand you the world on a platter. This is a sort of "strategic pessimism," that can help lower anxiety because you're always planning for negative outcomes. The video certainly takes a full-blown, humorous look at pessimism's benefits, but that doesn't mean it's not right a lot of the time.
