Do you carry the weight of your past mistakes, or have you learnt to let go and moved forward?

As I grew older I realized that alot of things really dont matter to me, no longer need to get involved with some people anymore. I am finally seeing that I don’t have to answer to anyone but myself. I still have a couple people who are always on my radar. I understand that I’m supposed to forgive and forget but those will be neither forgiven or forgotten. I don’t let those POS’s lay on my mind tho, they aren’t worth it.
