I certainly create a mess while I'm working, but I clean as I go. The last thing I do at the end of the day is put away any straggler tools and clean the floor. I like to start the next shop session with a clean and organized shop.I can't stand the argument from people who always say that people with ultra tidy workshops can't possibly make anything - because clearly plenty of people do, they just like a tidy workshop.
I would have to say, the best people / performers I have come across in business are definitely those who are hyper organised.
