If you are concerned about the world, the first thing you need to do is transform yourself into a joyful being.

If you do not do what you cannot do, it is all right. But if you do not do what you can do, your life is a tragedy.

If you are a sensible human being, you will naturally be loving and inclusive.  

Being exuberant, balanced, and equanimous gears you up for the highest possibility of life.

If you realize your life is 100% your responsibility, there is no room for being resentful towards anyone.
