Mistakes are like the memories you hide in an attic: old love letters from relationships that tanked, photos of dead relatives, toys from a childhood you miss. Out of sight is out of mind, but somewhere deep inside you know they still exist. And you also know that you're avoiding them.
You can change the place you live, your clothes, your interests, your friends, your religion and even your partner. However, if you forgot to change your mind, attitude, beliefs about the world, how you treat people and how you plan to be different this time around, why did you even bother?
