Is it alright to drop all your past failures and start over?

I was thinking of leaving my past behind. All the dumb stuff I did, the crappy people in my life, negative emotions, everything bad that’s in my life, I want to leave it all behind and move onto a new life.

I know my past will always be a part of me. My past makes me who I am, but holding onto negativity hasn’t helped me. The only things worth keeping with me are the painful lessons of my failures, and drop anything that isn’t beneficial to my wellbeing. Like the “friends” that stabbed me in my back. I don’t want to hate them anymore, but I also won’t acknowledge them. It’s forgiven, not forgotten.
