A long time ago I was in pre-med. Similar to the article, I got a 35 on my MCAT. I know a lot of physicians. They're all very smart (because you have to be to get into medical school). The vast majority of them are bored with medicine. They do anything they can other than see patients. Some invest in real estate, some manage other physicians in a group practice--there's one guy who built a small datacenter and runs a business selling electronic medical records systems as a service to other medical practices!
The point is--the practice of medicine kind of sucks. It's mostly the same things over and over, with a lot of paperwork thrown in. Med school lures in the young with the prestige attached to the magic letters "M.D." and because med school is an ultra-exclusive club for smart people. The sick joke is that after all the work and sacrifice and expense the job usually isn't worth it. If you want to be a doctor, imagine yourself working in subsaharan Africa helping the neediest, poorest people imaginable. If it doesn't sound like something you'd want to do, you don't like medicine enough for the career path to be worthwhile to you.
