Keep em. And what Kat said.
I've sold ALL my gear (well pretty much) twice in my life; at 19 when I went to University and thought I'd have no time, 2nd time at 26 when I left the University & got married and thought I'd have no time...
Now I have two kids, 3 and 7, and work full-time and work on repairing our house, but also writing a book (well two actually) and am in three bands. Just released a CD too.
Sure, sometimes I don't get to play that much, but I try to squeeze in at least an hour, preferably two, of guitar playing too and it suffices.
I might sell of some of my guitars if someone offered me good money, I have a couple too many maybe, but I NEVER will sell off any more other music gear except to replace it with something better.
