Nicely said fexo.
I know this is pretty cheesy, but the preface to the old Harrison's Internal Medicine made a huge impact on me when I was in medical school. I sometimes return to it when I need to regain my bearings... (please forgive the lack of gender neutrality. it's an old quote from the 50's).
"No greater opportunity, responsibility, or obligation can fall to the lot of a human being than to become a physician. In the care of the suffering he needs technical skill, scientific knowledge and human understanding. He who uses these with courage, with humility, and with wisdom will provide a unique service for his fellow man, and will build an enduring edifice of character within himself. The physician should ask of his destiny no more than this; he should be content with no less."
I think the salary for an internist or any IM specialty would be more than sufficient to satisfy modest if not almost luxurious needs. In contrast with professions in industry, I think most people (myself included) find it somewhat obscene to seek out extreme affluence in compensation for treating the suffering or the infirm. I chose to be cardiologist because I love the practice, and I chose academic medicine (with its relative paltry financial compensation) because I love science and teaching. I think most people will be a lot happier choosing fields based upon genuine interest and satisfaction. OK, I'm off the soapbox now. Sorry.
