FW: rewind botton or fast forward botton

I would get to rewind because something would do every time tou get better at on my classes and other thing to make me better, so when it comes top now i would be ready more for the stuff ahead  me, i wouldnt change the past i just of would made it better in my life for the hard hit that about to come for me to prepare me for the real life and hard times, and the home work i couldn’t finish that was hard to me to get them done.
