<p>Getting MPH is getting a bit popular- one of my friends is applying for several programs because she knows that med schools like to see something like that and also it’s a bit of a trial to see how much she actually likes medicine from a practical point of view.</p>
<p>Honestly, talk to more than ONE professor about their PhDs. Ask them about the worst and best parts about graduate school. As much they really, really hate to admit it, for most part, they did love graduate school. (Probably because their lives were secure…and funded, and now they’re on their own!). I’ve talked with a number of people with PhDs- both at my university, other universities, and in the field that I want to work in to figure out if it would be worth going for the PhD. At the same time, I had to test myself to find out how much I love doing research so I spent hours with my sources and my laptop 
Did I feel good at the end or just spent? I felt terrific!</p>
<p>Teaching is NOT the only option for a PhD as others have suggested. The only way that you can make your PhD work for you is if you LOVE research and then you won’t have one bit of regret about going to graduate school. Those who felt that their PhDs didn’t do them good probably didn’t have a good experience in graduate school. You’re going to go out there without regret and just take whatever is offered to you. (Unfortunately, having that PhD can and will create that “ivory tower” or an egoistic mentality…)</p>
<p>Good luck… you’re actually a sophomore so you have plenty of time!</p>
