People have to face regrets. Becoming mature means learning to accept what you cannot change, facing unresolved sorrows and learning to love life as it really happens, not as you would have it happen. When someone attaches unkindness to criticism, she's angry. Angry people need to criticize as an outlet for their anger. That's why you must reject unkind criticism. Unkind criticism is never part of a meaningful critique of you. Its purpose is not to teach or to help, its purpose is to punish. Life isn't supposed to be an all or nothing battle between misery and bliss. Life isn't supposed to be a battle at all. And when it comes to happiness, well, sometimes life is just okay, sometimes it's comfortable, sometimes wonderful, sometimes boring, sometimes unpleasant. When your day's not perfect, it's not a failure or a terrible loss. It's just another day.
