Have you ever heard this story about Itzhak Perlman? To summarize, he broke a string on his violin during a performance and - rather than get up and find another violin (an arduous task due to the fact that he has braces on his legs and uses crutches) - he played on making adjustments with the remaining 3 strings. In the end, he said "You know, sometimes it is the artist's task to find out how much music you can still make with what you have left."
According to snopes, the story is not true. When I heard that - I was disappointed.
But the message rang true once again when I heard Brushy One String.
