As economists have often pointed out, we pay doctors for quantity, not quality. As they point out less often, we also pay them as individuals, rather than as members of a team working together for their patients. Both practices have made for serious problems.

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.
