Be nice, for yourself.

Be nice to people. I don't believe in karma. I don't believe in a set of rules to follow. I do believe that respect is something you earn by being fucking nice to people. If you don't have respect you will not be happy. Don't get me wrong, I can be quite the douchebag. I do however, never say no when someone asks for a favor. That is the key to respect and ultimate happiness. Try it, even just for a day and check out the results. I'm not saying go as crazy as they did in the movie "yes man", but for a whole day do everything someone asks you to that isn't ridiculous. Don't tell anyone what you're doing, just help everyone you see that might need help. Open doors for people. Say hello to people you recognize. If you're friend asks you if she can borrow something say yes. If someone asks you for a favor fucking do it. If you appreciate someone, tell them. Smile as much as possible. That's essentially my personal commandments. Not because of right versus wrong, but it will make you happier yourself in the end.
