Unless you truly need the space the items occupy or the money selling it might bring, just stuff the stuff in a closet or other out of the way place. I often go through extremely long periods of non-modeling, but always return.
I stopped when I went to college, but then started building after I was stuck on campus on long weekends or other holidays.
I stopped when I left college and went into the Army, but I started again after more long weekends and holidays.
I stopped when I got married, but started up again when having children made it too expensive to go out and with the wife. Sitters got paid by the hour per child, we'd spend more on the sitter than on the evening.
I stopped after I started working again. Second shift hours for me, including commute, means I am out of the house from 2 PM to 1:45 AM. I'm in bed by 2 AM and up at 9 AM. Sometimes I go for weeks without building, because there's always something to fix around the house or yardwork before going to work.
It's nice to know I have something to tinker with on the table in my home office whenever the mood and time suits me.
