One of the best pieces of advice ever given to me by someone much wiser: "What other people think of you is none of your business." When you can embrace it, it's one of the single, most freeing things you can do for yourself. It's not easy. It may feel impossible. But I swear it's worth it. This ties in with "Do not live in regret." Let them think what they will, and let them go if they go.
