The ego doesn't know that the more you include others, the more smoothly things flow and the more easily things come to you. When you give little or no help to others or put obstacles in their path, the universe—in the form of people and circumstances—gives little or no help to you because you have cut yourself off from the whole. The ego's unconscious core feeling of "not enough" causes it to react to someone else's success as if that success had taken something away from "me." It doesn't know that your resentment of another person's success curtails your own chances of success. In order to attract success, you need to welcome it wherever you see it.
— Eckhart Tolle
