Answer for question 4602.

[Error: unknown template qotd]Every "mistake" I've made in my life either was unavoidable at the time, or eventually led to a better outcome than if I hadn't made it, or both.

The big "mistakes" I've made were due to mental instabilities that I have that weren't correctable until the proper medicines were invented -- and I was on them within a couple years of when they were approved for what I have.
Any regrets I have? Well, there are perhaps a few people I should have flirted harder with whom I am now out of touch. I'd thought of writing up some house rules that I'd come up with for GURPS and sending them off to PYRAMID magazine, and, had I done that, maybe I could have ended up writing a GURPS supplement at some point.

There was this one time where I was at a con where Steven Brust was the guest of honor, and I'd heard that he was hanging out and playing guitar somewhere, and I just was feeling tired and I didn't have my guitar with me. So, if I had it all over to do again, I'd have brought my guitar to that con, and made sure to go jam with Brust.

And at a different con, I'd heard that Amanda Palmer and Brian Viglione were hanging out in one of the rooms, and I didn't go hang out with them.

So those are my regrets. I didn't flirt well enough with two people I can think of after college. I didn't put together an article for a roleplaying game magazine. And I didn't jam with an author and hang out with some musicians when I might have had the chance.

That's about it, really.
