Vows

Do not live in the past. Past is done. It's over. Not going to happen again, unless you let it.
You can't change something that has already happened, so don't waster your time on it. Learn from it, move on from it.

Do not trust anyone. Be happy with yourself and learn how to trust yourself and no one else before you. Learn how to read people so you know how to deal with them in a proper manner.

Do not let other people walk all over you. You are an individual, rely on yourself. Be your own judgment and love yourself. You are the only person that can control your happiness. Don't give this power to other people, specially useless people.

Do no dwell on yourself for anything. Make a decision, do it, deal with it. No need to sit and wonder. If it outcomes well, Good job! If it does not, learn from it and be careful for next time.

Do not let people be part of your life who have hurt you, unless you can forgive completely. At the end of the day, you have to rely on yourself for everything. You come alone in this world and you go alone. No need to put up with people's BS! Self-Respect is key.
