Winchester's Law

When I was a kid my sister and I would watch M.A.S.H pretty much every day. I can say with some confidence that while I might not recall all the episodes I'm sure I've seen them all, and many of them twice. 

On the topic of focus though, I've often been in a situation where it has been necessary to express the need to do a job well. That is, not to hurry and get a job done so you can move on, but to do it as well as it can be done at the time. 

I call this Winchester's Law in reference to M.A.S.H. Season 6 Episode 1. Thats the one where Frank Burns leaves and Charles Emerson Winchester III becomes permanently attached to the 4077th. It's based on Charles Winchesters comment to Hawkeye as he is explaining his surgical technique. He says,

"I do one thing at a time, I do it very well, and then I move on."

This is, in essence, the road to greatness. Do just one thing as well as you possibly can, then move on. This is in contrast to doing 3 or 4 things reasonably well and maybe not getting it all done or of course, doing nothing.
