See if you can catch yourself complaining, in either speech or thought, about a situation you find yourself in, what other people do or say, your surroundings, your life situation, even the weather. To complain is always nonacceptance of what is. It invariably carries an unconscious negative charge. When you complain, you make yourself into a victim. When you speak out, you are in your power. So change the situation by taking action or by speaking out if necessary or possible; leave the situation or accept it. All else is madness.

Eckhart Tolle
