Not that I make money (or much of anything else) in my shop, but when I was working construction my boss always said "a clean jobsite is a happy jobsite." We kept things cleaned up and I can say without hesitation that it helped. Helped find things when we needed them, helped keep it safe for ladders or carrying things and generally just kept us from banging up a house as we were building it. By the time we were putting up trim, boots and toolbelts were off limits in the "finished" part of the house.
