The ego loves to complain and feel resentful not only about other people but also about situations. What you can do to a person, you can also do to a situation: make it into an enemy. The implication is always: this should not be happening; I don’t want to be here; I don’t want to be doing this; I’m being treated unfairly. And the ego’s greatest enemy of all is, of course, the present moment, which is to say, life itself.

Eckhart Tolle
