Regrets

How do some people claim they don't have regrets? I don't see how even the most cheerful people can live through life without regrets. I guess, when a person says he doesn't have regrets, he really means that he hasn't succumbed to his regrets. He has regrets, but he has accepted them and moved on. Regrets, if let loose to grow, can become all devouring black holes. They suck every sliver of hope and happiness left in you, leaving you despondent and restless. It is a strange state of restlessness, bordering on depression. It doesn't let you focus on things that are positive and can break this cycle of negativity, instead it prods you to continue down the path of self-destruction, leaving you worse than where you had begun. It's a vicious cycle at it's vicious best.
