Toyota developed a system called TPS (Toyota Production System) starting in around the 1950's which works to save seconds in so many ways (moving stillages closer to operators for instance - less steps), It's where phases like JIT (Just in time) and words like Jidoka and Kaizen were applied to production. I think it can be implemented in a person's life, as you point out. It's designed to save waste as well of course, but I thought I'd mention it considering your comment.
Anyway, I try to do this for myself at work and home.
Indeed...everyone should.
