Well put, I'm in the same boat. All my hobbies come and go as well but never get rid of them.
This corner, boxes of trains, that corner boxes of rc parts, that corner guitar parts, it's a vicious cycle.
I am thrilled to death however that I have found the love for my guitars again.
Off and on actually. I haven't touched mine this summer, hopefully I'll get the bug again one of these days.
I'm wanting to build another 1/10 crawler so I probably start buying parts right after Christmas.
