What IF....

I realize that this is really a dangerous game, but sometimes I like to play anyway, sorta like "If I ever won the lottery, I would.....".
Love Man and I had gotten into a "What If" discussion the other day and it really set my wheels in motion. All those myspace surveys with the question "if you could change one thing about your past, would you?' I don't think people really give that much thought and they think of one unhappy incident and say yes. I HONESTLY have no desire to change anything about my past. Even my Crohn's disease, as terrible as it has been. If I ever changed ONE LITTLE thing, it is quite possible that NOTHING in my life would be the same. If I hadn't met a certain shady, lying bastard in my past, I may would never have accepted a certain job where I met Love Man. I simply cannot fathom this. I won't. My life would seem empty without him (melodramatic, yes.....but so so true.) I may have met someone else and be happy, but I wouldn't ever be this happy, I just know it.
I mean, WHAT IF I had no regrets in my life, then I would have no experiences to learn from and I would never grow as a person. So I've decided that I will no longer play the What If game on my past, but instead on my future. I will use it as a compass to guide me towards my goals. For example, "What If I actually got my shit together, found some motivation and lost some weight? Would my Crohn's disappear, would I feel better about myself, would I have more confidance? These are all things that I want, and I know the logistics of how to get there, I just have a hard time finding the motivation. So, What if I found it? I guess it's sorta like visualizing your goal, but not quite.
So guys, What If you applied this to your life? Would it make a difference, do you think you would change???
