A close friend is considered one of the best neurosurgeons at one of the best hospitals in the country. Brain tumors are his specialty. I remember him once saying he was growing exhausted about his job and thinking of retirement, even when he’s still young. The reason being, most of the other doctors in his team were not very competent and he had to constantly review and correct their work. He’s not an arrogant guy but all the contrary, very down to earth. For him to say something like that is because the mistakes he sees have to be bad. Every time he tried to quit, the hospital threw so much money at him that he could not refuse it.
