What would you change if you could go back to your past?

These are the 3 themes that interests me, the writer can pick one 1) not fight the inevitable and hang on to what was. i wasted so much time trying to save the un-savable. 2)walk away from toxic people. I chose to ignore the signs and suffer for no reason, other tahn fear. 3) not try to be a hero. its not my job to help who did not want to help themselves. i ended up enabling the same selfish and destructive behaviors.
