Revenge is rarely a good motivating factor for any action. Revenge comes from anger, anger comes from - something else underneath the anger: hurt, lost trust, lost faith, unmet needs.
Running your life off of the idea of revenge is essentially allowing those you're seeking revenge upon to continue to control your actions. You are only taking those actions because of the people who hurt you.
Finding and addressing what lies underneath the anger that drives the revenge will allow you to make the decisions that are good for YOU, not for any other reason. It's not a fast process, but in the end, it is well worth it.
