Sure, bad things have happened to me from time to time, and, sure, I've made some bad decisions. I've done some things that I'm not proud of. But you know what? I don't regret any of it, not a thing. Because the things that I've done, the things that have happened to me - good as well as bad - have made me who I am.
For example, that time I went surfing. Boy, did I make a fool of myself! My wife has a video of me doing a complete somersault and bonking my head on the board. That was just before the Great White came up and bit off my leg. Ouchers! Of course, looking back on it, I shouldn't have gone surfing in shark-infested waters, and the chum-scented sunscreen was probably a bad idea, but still, that accident is part of who I am.
Or when I went scaling that crevasse by myself (big mistake!) and got my arm pinioned in between those two rocks, I figured it was about the worst thing that could happen to me. I didn't have any bars on my cellphone (natch) so I just waited around about an hour before the solution hit me. Saw your hand off! Like Nietzsche said, "Anything that doesn't kill you, makes you a lefty." Anyway, that accident is part of who I am now, and I wouldn't take it back.
Or when that mad scientist put the brain of his golden doodle inside my skull. Frankly, I can't remember how he talked me into that one. I was drinking tea with him inside his enormous castle, and next thing I know, I'm coming to on an operating table, and he's asking how I feel and waving a dog biscuit in front of my face.
When people say to me, "How did you get to be this way?" or "Stop sniffing my crotch!" I tell them, it's who I am. All those experiences are the rich tapestry that have woven the unique individual who is me.
