I don’t think M. Scott Peck was thinking of patient education when he said this. However, it clearly describes what is going on during the teachable moment:
“Our finest moments are most likely to occur when we are feeling deeply uncomfortable, unhappy or unfulfilled. For it is only in such moments, propelled by our discomfort, that we are likely to step out of our ruts and start searching for different ways or truer answers.”
— M. Scott Peck
So notice when your patient is tired...
