Honestly, I think that's a great point. I don't know if it's relevant, but I know a lot of people who could be better people, but they choose to be jerks and treat others badly, as if the universe owes them the chance to be happy. I think the best thing is to wake up and go to bed with a clear conscience, knowing that you only live for yourself and for the people who love you, without hurting anyone else. It's much more than that, but that's the basics.
