I accidentally signed up for a creative writing glass this term at school and it was probably the best mistake I've ever made. Up until that class began, I had been frustrated. I had a lot to say and -- believe it or not -- free jazz didn't quite get the message across. I felt that the indigence within would never be represented aside from some dissonant sounds. When I started taking the writing class, the professor helped me to shape my thoughts into words so that I could share what I had to say. While I'm still no expert, it has helped tremendously. Why do I write? Because jazz is not a universal language. If I want to share my thoughts and have them understood, the written word is the most applicable medium.
It really has been an incredible experience. What I'd suggest is writing about every day situations and throw in something entirely from left field. But I'm no expert so that could be way off.
