If you could start your life over, how far back would you go? Myself, I would only need to go back to the beginning of 2001. The ground rules: 1) You're not allowed to prevent any major historical event from happening; it might cause two universes to collide or something. 2) You're not allowed to save anyone's life; unless you were the cause of their fate. 3) If you go back, you have to stay there; you can't come back to the present. This would mean that you might have to relive some unpleasant events in order to change your own destiny, or to erase a personal tragic mistake.
