Regrets? I've had a few

So, something in the comments got me to thinking. In general, I don't have too much use for regret. I've spent a good portion of my life making bad choices and then having fun with it but living with the consequences. Yeah, planning isn't my strong suit but making the best of rough patches is a talent I've developed. So, while I don't necessarily regret my decisions, mostly because of the stories I have to tell and the fun I've had along the way, I might, if given the chance, change some things.

How different would life be, though? Would I look back and regret a life lived to other's expectations? Would I be the person I am now? Would I be, the worst of all possible fates, bored with what I'd done in my life? Maybe. There's no way to know for sure. But, a decision here or there, some delayed gratification, some wiser financial decisions and perhaps things would be better. Or perhaps, they'd just be ... different. I had a boss once who, after hiring me into his group, asked me how I liked it. "Much better than where I was at." I replied. He then said something that I've often thought about when I wonder if things would be different or better somewhere else, he said "Well, eventually, it will be just a different kind of suck."

So, what about you? Do you have any regrets?
