Do overs in your past are really thorny things to think about. Would you be in the place where you are now if you didn't have that experience? Would you be better off, or worse? And do you really want to risk it? The things that I've done, the things that I wish I could do over are mistakes that I've made that became lessons to me later in life. If I missed them, I would probably end up finding a way to make them happen anyways. One thing that I probably could do without, if I had a chance would be my relationships during college. One in particular which was very nasty I could probably do away with. But then again, I lacked the maturity and understanding to do it any differently back then, but now? Oh how I would erase all of that. I know exactly where and when I should have turned my back and walked away. The first fateful aborted meet-up, the one that fell apart because the person I was about to meet was a coward. I should have had more wits and saw that for what it really was instead of allowing a second chance and enduring what I had to endure.
But then again, that whole experience laid the foundation for where I am now. I enjoy my current life because I learned a lesson back then and grew because of it. Do I wish I could have skipped it? Sure. But if I did, I probably wouldn't be as mature now as I am having experienced that mistake. So there is a wish, but no will to carry it out.
