Thanks for the suggestions. Does anyone have any other blogs or resources?
You can google around, but the simple answer is that this is a "simple" question - you make money, and then you pay your debt off.
The slightly longer answer is that it depends on your answers to two questions:
1) Someone approaches you and tells you that, if you will work at their hospital for the next few years, after that they will pay off your
entire debt, but they won't pay you as much annually as other hospitals. How much less money are you willing to make to accept this offer?
2) Another person approaches you and offers you an investment opportunity with an average annual return of X%. How high would X% need to be for you to redirect half the money you were going to pay toward your loan to that investment? How high to redirect 75-80%?
You are going to read blogs that'll tell you to that you should delay paying off your loans for as long as possible and invest every spare dollar you have in the stock market. Numbers-wise, that's the correct strategy (though not without risk). Doesn't make it the "right" strategy for you, though. Similarly, if you are taking out $75,000/year for med school, by the time your finish residency that number is going to be a lot bigger than $300,000, and it very likely will make financial sense to go for PSLF with that number. But again, that might not be "right" for you. Everything depends on what you want to do.
No strategy is wrong. If the peace of mind of paying off your loans in 5 years is worth more to you than paying them off over 20 years and ending with a net worth several % bigger, no one will fault you.
The ultimate advice is not to worry about it, which isn't very reassuring. But plenty will change for you over the next 10-15 years, and your strategy will change with it. The best your can do is to save money where you can, focus on your studies, and still save time (and money) to enjoy life.
