Regret

"If you've grieved your losses, reclaimed your dreams and articulated your anger, regret will have made you the right kind of tough-and-tender: dauntless of spirit, soft of heart, convinced by experience that nothing based on fear—but everything based on love—is worth doing. Living this way doesn't guarantee an easy life; in fact, it will probably take you on a wondrously wild ride. But I promise, you won't regret it." Martha Beck
