How do I learn how to love when I hate and believe I'm better then everyone else?

Realize how you have learned from experiences in the past and how you changed because of it. Then, realize that people are on that same path of learning not to be such a dumbass (life has a way of buffing and polishing us all) and may not always do what you like them to do, but will learn the hard way of what benifits them. Then, realize that they are just 'different' and you are great enough that they need to catch up to you and let them learn themselves.
