Yep no need to relive it . use it as a tool to make you smarter, better and independent. I once had hate for someone and all it did was motivate me in the end to be strong, work hard and prove them wrong
The older you get, the more you realize you have no desire for drama, conflict and any kind of intensity. This is my favorite kind of grown up, the rest of you need to stop acting like teenagers and act your age!
