^^^ True indeed. I know a girl who is extremely intelligent. Went to all the "right" schools and is currently completing her residency at John Hopkins. She's great on paper but sucks with interacting with the real world. She focuses on being rich and we tell her that as a doctor, her first focus should be on the welfare of people. If not, she will never be successful. We believe that she puts more weight on being called a "doctor", which is not as impressive now as it was in the past.
You don't know how I wish I could agree with that, but health care is a business like any other, at least in the US, and in any business, the purpose is to make a profit, not the welfare of people. Doctors have to market themselves, too. First, and you could argue most importantly, they have to market themselves to a practice that is already successful and making money. Then, just as with any business, they have to market themselves to their patients, and that's where they can focus that sincere interest in the welfare of people that may have motivated them to choose a health care field in the first place!
But it doesn't end there. They must also continue to market themselves to their colleagues, to influential people who can help them get ahead, get published, get a research grant, depending on their personal areas of specialization, etc. Networking is really just marketing oneself, often in a pseudo-social setting, and successful networking means that you did some sucessful marketing of your flagship product - you!
They can even do pro bono work in their spare time, but again, like anybody else, their spare time is going to be scarce.
I believe business, especially the sales and marketing aspect, is a talent unto itself. And I'm not sure it has to do with what we traditionally think of as "intelligence," which somebody once defined as the "ability to see truth."
Someone might be a back office marketing whiz and never get rich, but someone with the ability to sell, and most important, the ability to sell themselves, will almost certainly be able to accumulate material wealth, no matter what field they are in.
And that talent, that gift, of selling themselves, the ability to "sell ice to an Eskimo," is the one single most important factor that separates the money-makers from the perennial strugglers, even though we can all tell tales of fantastically brilliant strugglers, who "know" more about the field than the Midas touch wealth builder.
Nor can we leave out those whose primary interest really does lie outside the arena of wealth-building, and those folks run the intelligence gamut, from box o' rocks to SuperGeniusNerdWonder!
