Five words can say so much.
"Milk the cow you've got."
When I first typed this saying in, autocorrect changed "cow" to "Dow". As they said in Georgia when I was a girl, "Same difference." Which really meant, no difference.
Pay attention to your own work.
Focus on what you can do, not on what you cannot do.
Focus on the task at hand.
FOCUS.
It's easy to have elaborate plans for the herd you don't own, and leave the one cow you do own unmilked. Sometimes I need to remind myself to focus. About 30% of this blog has been telling myself to focus. ;-).
