My first thought was, OH YES, there would be sooo many things that I would like to change or do differently if I were to be born again, BUT then like the movie The Butterfly Effect, I think back and wonder, what would be affected by those changes! Would I be the person I am today? If I hadn't married my first husband, then my son Joseph wouldn't have been conceived and born. Yes, it is true that the marriage didn't work out and I did end up marrying my first love after all but to have spared my first love the pain of me marrying someone else would have meant my first child would never had been born. So no I would not want to go back and change that.
As a teenager a was a wild child for a while, would I have wanted to change that? What did I gain from that experience? Knowledge, strength, and wisdom! I learned that alcohol is addictive and alcoholism was a part of my family's history. I learned I had the strength to quit drinking and not follow the pack! I gained wisdom which I have shared with my children about the abuse of alcohol and alcoholism. So NO, I wouldn't want to change that.
For every negative aspect of my past I can find a positive outcome down the line somewhere. I guess that is what trials and tribulations are all about! You have to own your past, live your present and look forward to your future, it is all yours and can't be changed, nor should it be!
