Bad days generally occur when a number of little frustrations happen in succession. On their own they might not be a big deal and you’d go on forgetting about them, but together they make you think the universe is plotting against you. These are false starts, and they’re often the root of bad days. When things appear to be going worse than usual, take a step back and look at what happened. You are not so important that an entire day has been set aside specifically for your personal misery. Dissect each moment, realize your being ridiculous, and make fun of yourself when you can. If you look at a situation realistically, you can sometimes stop a potential bad day before it starts.
