Live With No Regrets

So I was randomly contemplating this as I was walking back from spanish today while listening to my iPod. I don't really remember which song it was, but one line stuck in my head.."live with no regrets". Immediately I began to think how ridiculous that statement is.
If someone says "Oh my gosh, I totally regret such and such". Everyone's first reaction is to say "It's okay, you shouldn't regret anything you do." That my friends, is what I call bullshit.
Regret does not simply mean agonizing over a mistake for the rest of your life. Regret is what makes the world go round. It's our constant reminder of what we've done wrong, and hopefully we'll never make the same mistake twice. A person can not go through life never regretting anything. It is only human nature to wish we had not done something we did. There will always be the:
"I wish I hadn't dated him/her..."
"I wish I hadn't skipped that class..."
"I wish I hadn't said that..."
etc. etc.
Regret is not a life long thing, typically. If we didn't regret, would we ever learn from our mistakes?
There are many things in life I regret. I do not agonize of it. It serves as a reminder. So don't be afraid to regret. Don't be afraid to recognize your mistakes
