I believe we should all go back every now and then, "If we do not see where we have come from, we will get lost in a world of no progress"...
Its like being mad that you broke a dish on accident.... you'd just be mad and wasted all that enrgy on something you couldn't fix, so you pick up the pieces and move on, make new changes for the good; without walking on eggshells to prevent it from happening again.
I don't think it's possible to go back, though some people spend way too much time and energy rehashing their personal history.
yesterday was a long time ago.
what did you learn that made today so different ?
