"This is good enough."
The timing of these words is crucial.
I know some folks who say these words when they achieve the bare minimum. Barely good enough is still good enough. This was my response to most of my middle school classwork. I did just enough to make sure the teacher would accept it. I know teachers who have taught the same mediocre lesson for years and years without change. I guess it is good enough.
I know others who say these words only seconds before it is time for action. They reflect on past attempts and agonize over improvements. They revise and change. They practice and modify. They make improvements until the last possible moment, then they say, "This is good enough." These teachers continually look to improve everything they do!
Is your good enough good enough?
