This lecture transcript has been floating around now for a while, I thank a friend for forwarding it, one of those 'inspiring email forwards', but for musicians, and actually inspring. 

Karl Paulnack is on faculty at the Boston Conservatory, and he gave a commencement speech to the new students of 2004.  He likens the role of a musician to more of a therapist and medical professional than entertainer.  Although he is speaking to future professional musicians, I think the message is also relevant to anyone who struggles to learn to play.  The act of playing your instrument, even alone, is a powerful means of experiencing music.  all the benefits of music can come through even the most basic of practice regimens (if you make sure to keep you practicing fun!)

Here's a link to the article where I read it:
