Discipline requires more flexibility than most people think. We all know what we should do in most situations. Ignorance is rarely the cause of an undisciplined choice. The problem I have is that we become rigid in our thinking of when it is appropriate to give our best. When I am undisciplined, I have usually created a small window of when I am willing to give my best effort. I can disqualify a day as being a day to be disciplined for any number of reasons that create a less than ideal circumstance for the choices that I know I should make. It takes a flexible mind that accepts less than ideal circumstances and keeps going the way I know I should.
