The most difficult part has been stopping regretting not to be a better player and instead accepting my own limits: within those limits music has given me a lot of pleasure and, when I am deep immersed in the arranging process, often come up with musical ideas that really surprise myself.
I consider this a gift from the Heavens and can only guess what kind of elation must give composing a whole song, especially one of those timeless classics that we still enjoy to play.
