<p>I’m an impatient guy. I like business and finance more than medicine because of how much salary you can get in such little time. It only takes a mere three years out of undergrad to possibly earn up to $350k. If you’re on the medicine pathway, three years out of undergrad and you’re still in medical school paying a really high tuition. And even after medical school, you’d be stuck with a five year+ residency where you’d only get paid around $50k-$70k a year for over 70 hours of work per week. In medicine, you don’t really start getting the big bucks until you’re like 30 to 35. By then, you could still probably be paying off your medical school debts. 
However, in business and finance when you’re 35 you may as well be an IB Managing Director or Partner. You would be making over a million dollars a year! Some of the most successful MDs or Partners can make 20 million a year!</p>
<p>Anyway, this is just from a financial standpoint. There are many other factors to consider such as what you said, risk vs. stability. You can tell, however, that I’m drooling over the rewarding prospects of the compensation in IB.</p>
