"Don't move it twice" was a common saying when I had a summer job contracting. Don't move the wood off the truck, cut it in the bed of the truck, bring cut pieces in. Save all the dinky, random cuts for last, do them all in one go, instead of running back and forth to the truck every time. Clean from the top down, from the back to the front, so you don't have to clean something twice.

There's a lot of wisdom in the trades! I guess you care more for efficiency when it's your own energy you're spending, instead of some random computer's.
