The past can never be changed. No matter who or what you are, what happens in the past, it stays in the past. Everybody always rethinks the horrid memories of the past, and they always "What if?" What if this one small detail could be changed, how could it affect the present? What if I had or hadn't done this, how could it make the future better for me?
The truth is, you can't change the past. Everybody has a past, whether good or bad, everybody does have a history. People's pasts are just all part of the package deal that comes along. Some of the deals are cheaper than others, and some of the deals have more baggage than others. Some people just carry one bag around with them everywhere and others bury their many suitcases deep in the back of their closets. None of those things matter. All that matters is that everybody has a past, and that you just have to deal with it.
Humans always obsess over the past and worry how it's going to affect their future, but by doing that, they're further digging their own graves. Humans think that by changing the past, you can make everything better. They worry incessantly about the past and future; anything other than the present. The present will soon be the past, and if you make the right decisions the first time around, you can live in the moment. The past is over with, even though it may never be forgotten. The future hasn't happened yet, so by making the decisions you want to have a positive effect will change the future.
Live in the present; the present times is what needs dealt with now. Live in the here and now, and worry about now, not before nor later. There is no way to change the past, but by living in the present, you will ultimately change your fate.
