The best that you could be is.....

You can't be the best, so be what you are but understand them always.

You can't feel it when you don't do it

They hurt you (by "hurt" psychological hurts sometimes are more violent than physical) because they are jealous of you - they want to be like you but they can't. They hurt you because their life are not at all in the realm of your way of life, so they completely can't understand what that kind of life is. But that does not mean you are hurt - it's them who are hurt, because every one of us subconsciously, though not consciously, suffers tremendously deep down inside because his/her intention is extremely negative. When you are sincere, well-intentioned, and never hurt others by your words or actions, you can never be hurt - you are blissful inside because of your peace, and you feel pitiful to them who are struggling with hurts they do to themselves by hurting others. Violence does not only mean killing another.
