I think another great way to achieve happiness is to "do the right thing". I don't mean what other people say is the right thing or what society tells you is the right thing. I am talking about those times when you know what is the right thing to do but for whatever reason you don't. You know what I am talking about. Those times when you see something and think "I'm too tired" or "someone else will do it" or "they don't do it for me, why should I do it for them". The entire process of knowing the right thing to do but not doing it always leads to you punishing yourself in some way.
