I'm pretty content; work's good. Some of my colleagues are not content; work's stressful.
When training as a psychiatrist I was taught by an eminent chap who was colourful and very "medical model" in his approach.
His view of psychiatry was that it's all about misery.
He reckoned folk wouldn't be seeing us if all's well. He reasoned that we only get involved when there's illness and handicap from that. Years on, the notion that psychiatry involves helping those who have a change in health and change in function as a result of this really isn't so different from what he described.
It's odd, to my mind, that folk in the same job, in the same area, can do the same work but some find it vibrant and worthwhile, yet others see themselves mired in misery.
". . . for there is nothing either good or bad, but thinking makes it so."
