A triolet inspired by this Eckhart Tolle quote:

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 a victim. Leave the situation or accept it. All else is madness.
