What if you had the ability to travel backwards in your personal timeline whenever you wanted? Would you choose to go back many years and relive your life, correct whatever mistakes you made recently, or just try to correct all of your mistakes?
Personally, I'd use the rewind button to be as impressive as possible. I'd try something amazing, and if I failed, rewind. I don't think I'd want to go backwards in my life, but I'd use the rewinds to live my life from now as well as possible. It would be tempting to use the rewinds to do something unethical and then cancel it out, but as far as I'm concerned doing something bad and then rewinding would still cause suffering.
