I once sold everything I had in my studio to feed my family... I hatged doing it but if that is what you need to do, dig deep n rethink your priorities.
Now 40+ years later I'm doing very well for myself n can buy everything over again but.... I'm still telling people "I had one of those, sold it cheap in the late 70s." I get the rollie eyes n yeah yeah yeah we heard that one. Wish I hung onto my Leicas!
