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.

One of the reasons people might be fallible, why we might fail to do what we try to do isignorance, that we have a limited understanding of the laws of the world - the physical laws that govern the world and of all the particulars of the world upon which those laws work. And then there's ineptitude, meaning that the knowledge is available, but individuals fail to apply it correctly. The third source is "necessary fallibility." That is, we're never going to be omniscient, there is some knowledge that we will simply never achieve, and there are limits to what we will be able to do.

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.

Better is possible. It does not take genius. It takes diligence. It takes moral clarity. It takes ingenuity. And above all, it takes a willingness to try.

Writing lets you step back and think through a problem. Even the angriest rant forces the writer to achieve a degree of thoughtfulness.

What about regular professionals, who just want to do what they do as well as they can?

You may not control life's circumstances, but getting to be the author of your life means getting to control what you do with them.
