If you wish to change the past then you are going to alter your future. Things that happen to you in life happen for a reason. Whether they are good or bad. Just think if you would have never went to the store that evening to pick up some milk, would you have ever met your wife? Exactly! Even if the situation is bad, good always finds its way through.
So if you have always had it implanted in your mind that you want to change the past then you should take it out because if you could change time and changed one little thing, then everything is going to be changed and you my not like it.
Another reason things happen in life that may seem bad is that you don’t repeat history. Why do you think we learn it? Its so that when it comes to a time similar to an event that happened in your past that you did not like you remember what you did wrong and do it right or what ever came your way that was bad, you avoided it. By that, you do not repeat the past and learn from your mistakes. So be glad of what you have here before you and that what happened in the past happened, for good or the bad.
