I Should (Not) Have Done That

What's one thing you regret doing, or not doing?

my regret or regrets for that matter are simple; I regret not taking more risks. I'm not talking about jumping of a plane type of "risk" the risks you take with life, with people. Not big regrets, simple things. Its silly but for example not talking to a certain person or being honest with them. Things like that. I regret not having enough courage to do those things that I deeply wanted to do.
I know people say " don't dwell in the past. what's done is done." And honestly I don't. It just when you look back on your life you can't help but wonder what you're life would have been like if you did that one thing. If you would have a better life. On the other hand (though it seems cheesy) I am thankful for these regrets because I have learned from them, in a sense? I know now that there are somethings that you just have to do. period.
