This essay by Toni Morrison is fantastic, and you should read the whole thing, but I’ll quote one section here — Toni’s four rules for work:
1. Whatever the work is, do it well—not for the boss but for yourself.
2. You make the job; it doesn’t make you.
3. Your real life is with us, your family.
4. You are not the work you do; you are the person you are.
