You may not control life's circumstances, but getting to be the author of your life means getting to control what you do with them.

When I do an operation, it's half a dozen people. When it goes beautifully, it's like a symphony, with everybody playing their part.

After readinf some essay on the nature of human fallibility, I was very aware that we are the recipients of a huge amount of discovery over the last century. Medicine exemplifies this. And that has transitioned us from a world in which people's lives were mostly governed by ignorance to one that's constrained by ineptitude. A century ago, we didn't know, for instance, what diseases afflicted us, what their nature really was, or what to do about them. And that has changed.

You know, 97 percent of the time, if you come into a hospital, everything goes well. But three percent of the time, we have major complications.

Sometimes we can offer a cure, sometimes only a salve, sometimes not even that. But whatever we can offer, our interventions, and the risks and sacrifices they entail, are justified only if they serve the larger aims of a person's life. When we forget that, the suffering we inflict can be barbaric. When we remember it the good we do can be breathtaking.

Don’t let yourself be. Find something new to try, something to change. Count how often it succeeds and how often it doesn’t. Write about it. Ask a patient or a colleague what they think about it. See if you can keep the conversation going.

Coaching done well may be the most effective intervention designed for human performance.
