I write primarily because I need to. I occasionally derive some amount of joy from writing when the topic is one I am passionate about, but for the most part I write out of necessity. I plan on majoring in either finance or accounting and working my way up through the ranks, with aspirations of one day being a top-level executive. This will demand many things from me, and one skill that will be very important is my ability to write. Specifically, my ability to convey information clearly and succinctly is a must.
Because of my goal, I write almost exclusively in a formal style that would be suitable for communication with business associates. While personal stories and narratives are easier to write and assist me in introspection, formal writing as a means of communicating is significantly more important to me. Writing a good paper and receiving an A is a very satisfying feeling, but I write to set myself apart and to make me a more appealing job candidate one day in the near future.
