If I could live my life over the only thing I'd change would be to not have sold any of my guitars!! ( or Basses and amps) I'm sure my wife would not agree with this!
More good luck than good management, but I haven't sold a guitar, microphone, or stomp box since the summer after high school.
I did trade a guitar once, but I still play the 12 string I got, and probably would not have played the Jackson that I got rid of much - just not my sound. Again, more luck than anything else.
I had a bunch of gear stolen after high school, including a truly lovely 68 Les Paul Deluxe and a Dan Armstrong, and I really would love to have those back. They also got some other gear, but nothing terribly noteworthy.
After the robbery I started to buy into my parents suggestion that this rock and roll thing was kid's stuff. They meant well, I know, but it really wasn't the advice I needed. I sold an Echoplex for like $35, an AIM's 6x10 combo amplifier for peanuts, and some other stuff, also dirt cheap. As luck would have it, I could not (this was 1977) give away most of my pedals, so I still have them too<G>!
Sometimes my wife suggests that it is just a foolish attachment, but mostly she understands that they are all different, and they are all cool in their own way. The oddest - at least to me - is my first "real" guitar, a Mosrite Ventures model - nothing sounds like that. I don't play a lot of surf guitar, and I've been offered some silly money for it, but then I play it, and I decide I'll keep it around for a little longer in case I suddenly need it. OK, that is probably silly.
