Most of the time, regret seems like a gift - a reminder of what I did before, and why I don't want to do it again. There is an important difference between regret and unnecessary guilt. I regret not doing the little more that I should have done so that I could be an Eagle Scout. That is something I cannot change, but I regret it because it was a stupid decision. However, I do not feel terrible guilt whenever I think about the subject. Rather, I remember what happened in that situation, and I resolve to finish what I have started, even if it is difficult. Regret can be a powerful motivational tool.
In regards to why I have done many things I regret, I find that most of them were influenced by one or more of the following factors: peer pressure, laziness, selfishness, and ignorance.
Cyotie, as LDS said, I am so sorry you had to suffer such a loss. I hope that you are doing ok, and if not I hope you can search for and find help. Roz, from all of the posts I have read from you, I think you are an amazingly strong person with a lot of courage. And Howe, I also have admiration and respect for what you have to say, and I agree with your post. Tenahoff, I also agree with you, that I would be so much better off without having experienced some of the things that I have, and when I try to "warn" someone about something I have gone through, it is out of concern and a sincere desire to spare them the heartache that I have endured from the choices I have made. I have done some things that I definitely regret, and would be absolutely mortified to post on this board. But I will tell you that most of the major mistakes that I made were my attempt to stop my pain and suffering. Another reason is that I desperately wanted love and to be accepted. That may sound very sad and despairing, but I have made it to a place where I am very content and happy.
At one time in my life, I remember becoming involved in the National Lottery's "Play Whe." I used to play it about three times a week and occasionally, I would actually win about three measly dollars. One day, I thought about playing number 12 but decided to stop gambling and deposit all the money that I would waste on "Play Whe," in a savings account. Of course, that was the day when the number 12 was drawn. I could have won a lot of money but I didn't! Well the good news is, at least I have a healthy savings account now!
