Opening my eyes through graduate work
Going to school is not just work and learning things that you will never use. One of the things I discovered when I started my Graduate career education was that I could pick my classes and study the things I was most interested in learning. Sure they still had the required core courses but I could approach them from my viewpoint and use them to learn more about my chosed field. By my third year I was taking courses that I would have had no interest in two years earlier. The more I was learning the more I wanted to learn about other subjects.
