I'm posting a response to your question here so I don't start a flame war.
I was in the same boat as you a few months ago. I became interested in economics through the Mises Institute and considered myself a Rothbardian but I've changed my mind recently. As I learned more about mainstream economics, I realized that most of the important Austrian insights had been taken up as part of neoclassical thinking. Austrian economics isn't coming back because there is really no such thing as Austrian economics anymore. Mises and Hayek are great thinkers and I would recommend their writings to anyone but there is more out there. I wouldn't get too hung up on the fact that people don't use the same terms Mises used, for example.
Good luck in school.
