Never thought about quitting on my 55. However when I am working on a fun project,it is always best to just put the tools away for a day or so,when things start going rough. Then go back to it later,at which time things go much better. I never put myself on a have to schedule. If I dont get er done today theres always tomorrow or the next day.This is not like working on my daily driver which needs to be up and running tomorrow morning.
