See if you can find "The Creative Fire" by Estes. SHe talks a lot about the cycle of the creative artist. It always ebes and flows.
Have been doing this for over 65 years and in my mid 30's i put everything away and thought about selling it off when a friend offered to buy it and when I came to my sense sell it back .
I didn't take her offer, but I did have a period of several years where I just didn't care about working. However, since that time, the "down" time varies but I never think of selling it all and walking away.
Try to find something totally different to work on, something that makes your heart sing (certainly not models )
