Whatever the situation that vexes you the most right now, let go of the vision of how it ought to be. Surrender every shred of expectation. Do what needs doing but do not expect a reward. Do not dread the pain and suffering. Let go of the outcome. Offer it to the Universe/ God and trust.
“When you arrive at non-action, nothing will be left undone. Mastery of the world is achieved by letting things take their natural course.”Tao Te Ching
