In every industrialized nation, the movement to reform health care has begun with stories about cruelty.

At times, in medicine, you feel you are inside a colossal and impossibly complex machine whose gears will turn for you only according to their own arbitrary rhythm. The notion that human caring, the effort to do better for people, might make a difference can seem hopelessly naive. But it isn't.

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.

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.

This is the reality of intensive care: at any point, we are as apt to harm as we are to heal.

Developing a skill is painful, though. It is difficult. And that's part of the satisfaction. You will only find meaning in what you struggle with. What you struggle to get good at next may not seem the exact right thing for you at first. With time and effort, however, you will discover new possibilities in yourself-an ability to solve problems, for instance, or to communicate, or to create beauty.
