Let go of the past. There is no point in dwelling on it, because you can't change it. Too many people (myself included) stay focused on what's happened to them in the past or the choices they've made in the past. You have to let it go, or it will detract you from the present, thus affecting your future. Let go of all the things you would've done, could've done, or should've done. Let go of any guilt associated with the past. Let go of the unnecessary burdens others have placed on you. Let go of how things used to be, and accept the present. Let go of your mistakes, but don't forget them. Instead, learn from them.
