I chose surgery because I thought that perhaps this would make me more like the kind of person I wanted to be.

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.

Human interaction is the key force in overcoming resistance and speeding change.

Just look at the list of who the lowest-paid people are. Pediatricians are at the bottom. You would also look at internists. You would look at psychiatrists. You would look at family physicians, HIV specialists. People who take care of chronic illnesses by seeing people carefully over time, those are the people who get the least money. The people who have the most are people like orthopedic surgeons, interventional cardiologists. And my point isn't that there is something wrong with heroism.

You want to ensure people can do it right 99 percent of time. When we have to fire one of our surgical trainees, it is never because they dont have the physical skills but because they dont have the moral skills - to practise and admit failure.

Once you start to ask patients about their priorities, you discover what they're living for. Once you uncover that, it helps you, as a doctor, decide what to fight for. And when we do that, we often end up identifying limits to the kind of care that people want. One's assumption is that these people are going to live shorter lives, but what we're doing is protecting quality of life. In doing so, you sometimes end up helping people live longer. Certainly, you help people live better days and with more purpose in their lives.

My biggest fear, that 27 percent of Americans under 65 have an existing health condition that, without the protections of the Affordable Care Act, would mean they would - could be automatically excluded from insurance coverage. Before the ACA, they wouldn't have been able to get insurance coverage on the individual market, you know, if you're a freelancer or if you had a small business or the like.
