3) The way you should be thinking about the program is like this: it’s a chance to spend five years doing nothing but studying your favorite subject in great depth while keeping adequate health insurance and avoiding debt. You really won’t have either the time or the money to do very much else, so you had better really love this subject. You remember that episode of the Simpsons where the devil’s ironic punishment for Homer is to force feed him an endless stream of donuts, but gets frustrated because Homer never stops loving the donuts? Well you have to love your subject like Homer loves donuts, because that’s going to be you. If you do love it though, you won’t even notice being broke or studying all the time.
