The question, "What would you advice your younger self?"

To be honest, I wouldn’t be who I am today if I didn’t go through the path I did exactly as I did. Could I save some heartache? Maybe. Could I learn boundaries earlier? Probably not. Younger me was gonna figure life out his way and ok with facing consequences from mistakes. Younger me didn’t like warnings or “learn from my mistakes” speeches. Younger me was confident, didn't care what someone thought of me I still don't. What am I supposed to tell younger me that would matter without altering the present version of myself?
