Thank you very much for the insightful comment. I would say that you're more or less correct - I have experienced moments of great connection with music, especially during performance. However, isn't it great joy to live through writing, rather than great labor? Isn't realizing one's inner thoughts more fulfilling than anything else?
While writing can indeed produce a profound impact on the writer himself, unless the subject matter is deeply personal to the point of pain, I believe that the joy of self-expression can overcome any suffering.
