My life took many turns, I had gotten into this near the end of my previous marriage, honestly because it reminded me of my father who passed young.
I left almost 12 years ago because I had to get rid of everything in a move... life continued, things settled a bit and I returned. Starting from nothing and my wife, who saw me give everything away for the move and no finished models said I had to finish them this time, just not "collect".
I sure miss my parts stash, but there you have it. When I left before, everyone bemoaned the death of model building but I see a Renaissance now, especially with 3d printing.
The only thing I see as detrimental, is not having a 10 year collection, rebuilding parts for even a couple models (I can't seem to do stock builds...) is expensive!
