Look at what you are now, not what you were. Listen to what the people who care about you have to say about you; the words of strangers and the devil within you mean nothing. Learn from your mistakes, don't let them trick you into thinking you can never change. Get help when you need it in any way you can, do not fight your battles alone; even a hero needs a hero. Do not constantly regret nor worry, for "regret" is a rope that holds you back, and "worry" is a wall that keeps you from moving forward. Love yourself, and your love for others will only multiply, not subtract.
