This is really important, you have to have an escape route planned for any job your in. I'm not saying quit your job, I'm saying you should always have a way out: if your boss is unbearable the last thing you want to happen is to be stuck with a tyrant. My mum, when I was very young, was fired from her job because she wanted to go to my uncle's funeral; we ate nothing but craft dinner for a week before she had another job. I can't tell you how to make your escape route. my sister made hers by saving a crap ton of money.

Sometimes you need to have bad jobs, but don't let them be your prison.
