I promised myself that I wouldn't have a bad day for the rest of my life. If someone was wasting my time, I'd excuse myself and walk away. If a situation bothered me or refused to get solved, I'd shrug and move on. I'd squander no energy on petty annoyances, poison no minutes with useless regret. I'd play music at any hour of the night. I'd make a point of noticing the smell of the air, the shifting light on the mountains.
