Complaining is one of the ego’s favorite strategies for strengthening itself….

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, A New Earth
