Here’s a project asking people to list five things they do to stay sane. I’m going to arbitrage and ask only for one thing you do to stay sane. Please leave your answer in the comments.
I try to listen to beautiful music at least once a day, I don’t check my portfolio even in the best of times, I hug a loved one at least one more time than was expected (with adaptive expectations this is hard to sustain over time but I have my tricks), and also I avoid television advertisements as much as possible. That’s four, you need only offer one.
