“Regret is an odd emotion because it comes only upon reflection. Regret lacks immediacy, and so its power seldom influences events when it could do some good.”
The funny thing about emotions and feelings are that they can’t really be rationalized. The way I feel today may be different than the way I feel next week. A choice I make today may not seem as optimal after a few days of examination. I’ve always been a huge advocate of “learning to live with your decisions” so you don’t have room to regret. Regret is doubting your choice but, for whatever reason, it was the right one to make at that time. Unless your just notorious for making bad choices.
