Why go to med school... Well the answer is easy...you will enjoy what u do because of the variety of specialties available....

For instance if u don't really like working with others.... pursue pathology
if u have a big ego ....... pursue plastic surgery
if u don't want to work nights there are many options...derm,opthamology,even anes,

i'm a hospital based doc so my situation can vary based on supply / demand but u can find the perfect job for u... i have certainly paid my dues but currently
i have no overhead , no billing worries ,i rarely work past 7pm, guaranteed income , time to serve the medical staff, 10 weeks vacation,and i make 200k a year on other medical enterprises outside my primary job

IF money is the primary goal there is still hope, remember some of the disconcerted docs are ones that have been around 15 years or so because they are making less today..particularly surgeons, gi,neuro, vascular etc while primary care has risen....However the more enterprising specialists find other avenues of income (independent centers, newer procedures like lap bands and so on) , i swear the urologists re-invent the same procedure 3 times a year....

Anyways if u have a good business sense medicine could be an avenue for u..u're income will vary but in reality one only need 8-10years of 600+k income to be set..

good luck and hope u achieve u're goals
