if you have a chance to rewind time and change one thing in your past,what will that be

if you had the chance to rewind time and change something in your past what will you change for me i will change the university i chose when i left high school to a less competitive university and am sure i would have being in college now but i hope i get admission this year so tell me what would yours be.

Not buying so many useless games, toys, and all those things.

If I could rewind time,I would screw the guy who stole my girlfriend.Then again I still have the choice to screw him lol!Oh well the past is the past.I'm looking ahead to the future.

If I could rewind the time, I would try to be a better man. I did so many mistaken things to the people I love...I have many regrets :-(. So try to do the best things when you can, because you can't rewind time.
