Teufelhunden,
There are two reasons your essentially f---ed.
1. You think.
2. You hope.
If you didn't think, then you wouldn't think, "man, med school is really stupid. I'm going to forget everything they're making me memorize within a year and it will have no impact on how I practice medicine." And you also wouldn't think, "What is the point of this suffering?" You also know of other professions, like the marines, where one can have a rewarding career. So you wouldn't think, "other professions, while having learning periods, do not require this degree of nonsense to become proficient." During 3rd year, you won't think, "boy, my arm hurts from 8 hours of retracting, wouldn't a pulley work better?"
If you didn't hope, you wouldn't be bothered by the fact its going to take you at least six years from the start of med school until you can start having a normal life - assuming you choose an easy specialty. This will delay normal life goals: starting a family, seeing said family, buying a house (unless you live in a fly-over state or ghetto), making money (because you will be paying back loans. While all your friends benefit from compounded interest in their IRAs, you will quickly discover the devestation this can bring when it works against you).
Solution, other than giving up medicine (even after getting an MD, you can still do it!): give up thought and give up hope. Very buddist, I know, but to their credit:
If you give up thought, you will be able to plow through the books, rock out on step 1, kiss enough ass (thought entails self-introspection and without that pesky little bug, you won't have to think bad thoughts about yourself while you bring in coffee for AM rounds, or lie and say "Oh, it's between ortho and family practice" while on family practice), and be SO HAPPY when you match at a top spot in __________, where the suffering will continue. But by then you'll be so thoughtless, it won't matter that debt accumulates, family is put off, and you're bringing home 5 dollars an hour. But by then there'll be no alternative - you can't think of one.
But while giving up thought will give you some success and blunt the suffering, giving up hope will bring it home (to your studio apartment in the slum). Without hope, if you have a lot of debt, then having to choose a specialty based on this won't bother you too much. During residency, you will no longer hope to get off for Thanksgiving, X-mas, New Years, any weekend. You will no longer hope for a 80 hour week. Without hope to spend time away from the hospital, you will reap all the rewards of practicing medicine in the 2000's: spending hours defending yourself from lawsuits in advace by writing 4 page notes, the (thoughtless) intellectal satisfaction of the reflex CT scan revealing something bad, or correcting the potassium from 3.2, doing the 600th lap chole. You'll have the emotional satisfaction of having 5 discharges in a day, plus one death and one crach to ICU, halving your census - of course - so you have more chances to admit and write more 4 page notes.
Without thought and hope, you can go on to practice happily, dealing with all the insurance, scumball patients and their lawyers, costs of doing business, phone calls. After all, you'll be a DOCTOR, and people must respect you! You wear a long coat and the MD after your name. You can boss nurses around, after residency. Without thought, you won't see that this arrogance is silly.
Good luck to you in ridding yourself of these two medical character faults.
