"Bedded in too comfortably, people will neglect the higher standard; it is by arousing self-consciousness that the worker is driven to do better."

Continuing in the Craftsman, Sennett is asking what it is that gets people to do good work. He explores several problems in oversimplifying an answer and then draws us to what he calls a "liminal space between problem solving and problem finding." It is here, he seems to say, that self-awareness elevates craft.

Perhaps what makes a craftsman great is thoughtfulness, a cyclical and perhaps even obsessive reflection on what you're making. It sits in you, inhabits you. You consider it, then do, then reflect, and do again.
