Expertise is the mantra of modern medicine.

What is needed, however, isn't just that people working together be nice to each other. It is discipline. Discipline is hard--harder than trustworthiness and skill and perhaps even than selflessness. We are by nature flawed and inconstant creatures. We can't even keep from snacking between meals. We are not built for discipline. We are built for novelty and excitement, not for careful attention to detail. Discipline is something we have to work at.

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.

Sometimes we can offer a cure, sometimes only a salve, sometimes not even that.

When we forget that, the suffering we inflict can be barbaric. When we remember it the good we do can be breathtaking.
