I've written a little over 150 words, but my main concern is whether the content is too broad for the short essay and if I should use this as a springboard for my long essay.
What makes creating music so appealing? For me, it is its dynamic and expansible nature of discipline. When I first started playing piano at the age of six, I never once thought the instrument would become such an integral component of my life and schooling. Many hours of arduous practice, however, have reversed that outlook. Looking back, I have found an intangible link between the effort spent in practicing and my work ethics in academics and extracurricular activities. Practicing, to me, is not a chore or about "getting the job done"; instead, it serves as a path that allows me to better a skill that I have already started to acquire. Analogically, an active pursuit of knowledge is, in my opinion, the optimal method of learning. I believe that if I am to start anything, I am going to finish it - not create a half-baked product that will not only disappoint others, but also myself.
You might want to personalize this essay a bit. At the moment, it sounds very much like the sort of essay anyone who has learned to play the piano might write. Can you say something about your experience that would be personal to you, and that would show rather than tell the qualities you describe in the essay?
