We recruit for attitude and train for skill.

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 can't make a recipe for something as complicated as surgery. Instead, you can make a recipe for how to have a team that's prepared for the unexpected.

People who reach certain levels of frailty, more important than getting their mammogram, more important than getting their blood pressure tweaked, they're at high risk of falling. If they fall and break their hip, they not only die sooner, they die miserably.

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.

The striking thing is that WHO doesn't really have the authority to do any of this. It can't tell governments what to do. It hires no vaccinators, distributes no vaccine. It is a small Geneva bureaucracy run by several hundred international delegates whose annual votes tell the organization what to do but not how to do it.…The only substantial resource that WHO has cultivated is information and expertise.

Practice is funny that way. For days and days, you make out only the fragments of what to do. And then one day you've got the thing whole. Conscious learning becomes unconscious knowledge, and you cannot say precisely how.
