I hate to hear that Airfix Omnibus might have made you go burnout. I loved what you did with that model, I really did.
This topic comes up from time to time, Mark. My , I think that for some of us, the hobby is an on-again, off-again thing and I don't think that is a matter for concern. But it is apparently bugging you so I hope you get some good ideas here.
One bit of advice I've gotten from folks here is go clean up the bench. That has worked for me a couple times. But you just posted a pic of you with your bench in the background and it looks ridiculously organized, so that might not work in your case.
edit: I didn't mean to disregard Real G and Tojo's posts above, I guess we cross-posted.
