Well, t510, I am not sure where to start. You have some misconceptions of medicine. Doctors in private practice have to run their own businesses in addition to seeing patients all day and dealing with hiring and firing staff, etc.
It is not an option to "be an asshole" and practice medicine. It is a very people-forward field and you will daily be dealing with referral doctors, nurses, patients, patients families, and potentially supervising PA's or other extended providers. Check out sites like "health grades" or "vitals.com" and you will find that patients can post in public anything they like about their doctors...anonomously. (whether it is true or not). The business side of medicine (surviving and making money) for most of us depends on word of mouth of other patients. So, far from being a jerk, medicine is all about remaining calm, sometimes in the face of verbally abusive family members, nurses who question your judgement, patients who are uninformed or unreasonable, and staff that may have issues of their own.
If you have great communication skills, you are going to need them, studies show physicians who have a good relationship with their patients are less likely to be sued.
You asked for negatives about the profession:
1) high cost of malpractice is driving many out of medicine (after 8 or more yrs of med school and residency, you are likely to make less than the 200,000 you quoted)
2) Declining reimbursements, doctors are given effective pay cuts by managed care on a regular basis, the only way to make the same pay is see more patients in the same amount of time. See the thread: medicaid mills
3)High stress, if you get it wrong, you may affect someones life forever. Even if you get it right, you may be sued for an unforseen complication.
4)No time to yourself. Most Docs I know have scant social life and have difficulty at home due to limited family time (see threads all over this forum ie: "what have i done".
5)The current age of internet information makes everyone feel like an "expert". The respect of the "brilliant" physician is not what it used to be. Be ready to have your opinions and recommendations questioned all the time.
6) Suicide. No I am not being dramatic here. the statistics are clear that physicians are at a high risk of suicide. Sometimes no matter what you do someone young or unexpectedly acutely sick dies in your care...or you make a mistake... or you are drowning in debt from medical student loans (200,000+).
Or your marriage and family are crumbling because of the demands of your profession...
Having said all that, taking care of patients is a privilege.
you sound like you have the smarts and the work ethic.
Don't go into medicine for the money, or the image of the"powerful and brilliant" respected person, or because you are burnt out from long hours. You will find the pay, the hours and the admiration not up to your expectations.
The main reason to pursue a medical career is because you care about people, you can put others needs above your own (even if you are tired and cranky, or sick) and you feel it is what you were meant to do with your life here on earth.
Many "would be" career changers need some time off to get perspective, you admit to being burnt out. A vacation or short leave may be the perspective you need to see your current job clearly.
Working as a volunteer in a hospital would be a start too... if you really feel you have the calling. (and would look good on your application). If you find the work stimulating, great... on the other hand if you find dealing with the public difficult (and getting puked on as a side benefit (remember these are sick people-not at their best)...then you know. Following a Doc would be great, but remember that in residency you will have your share of transporting patients, being puked and bled on and most residents would not describe their jobs as "glamorous". Volunteer in the local ER and meet the public and see if you have the desire to serve people.
I meant this to be realistic, and not discouraging. If you really want to be a doctor, there is a great demand. Just make sure you get some exposure to patients before you begin such a long and arduous journey, so that when you get there it will be a place you are happy (most days) to be
