A failure often does not have to be a failure at all. However, you have to be ready for it-will you admit when things go wrong? Will you take steps to set them right?-because the difference between triumph and defeat, you'll find, isn't about willingness to take risks. It's about mastery of rescue.

We now have 30 percent, for example, of Medicare patients who are seeing doctors who are rewarded for doing this kind of work, like high blood pressure control. So, the Affordable Care Act has pushed this direction down the road.

When we lived in a society where we had large families that lived together, especially in agricultural societies like my grandfather and father grew up in, the result is you always had family around to take care of you.

Go back to the '30s, '40s, '50s, and it was the discovery of heroic interventions, the ability to cure people with penicillin or do an operation to stop disease that was what saved the day. Primary care physicians couldn't do all that much that really demonstrated a difference. The people who control and work with you to control your blood pressure, they're not rewarded for doing that or to be innovative about doing that. So, the result is half of Americans have uncontrolled high blood pressure, despite seeing clinicians.

One of the consequences of if the Affordable Care Act is repealed, is that all of us now are at risk of being a preexisting - of having a preexisting condition waiting to happen. Life, increasingly, is a preexisting condition waiting to happen, now that we have more and more of this data available.

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.

Culture matters. Of course, if physicians are rewarded or penalized for their service and results, the culture will change. But the key values we doctors are being pressed to embrace are humility, teamwork, and discipline.
