If I could start my life over, I would do it in a heartbeat if I meant I got a second chance. It means I get to make different choices and not the same choices I made before.
If that meant my current life had to come to an end to start over, then it's something that I would willingly accept.
There are decisions that my past self has made that I have since regretted. I am not the same person I was a few years ago, and I have changed since then. I wish my past self had deeply thought about the consequences before making those decisions.
