When I was in college I used to write little ditties and short stories and poetry for my friends. Writing a book is another thing. It is so much different from my traditional day of dirty fingernails and greasy hair and hot pans.
Those little nimble musicians of the air that warble forth their curious ditties with which nature hath furnished them to the shame of art.
There are so many opportunities in life that the loss of two or three capabilities is not necessarily debilitating. A handicap can give you the opportunity to focus more on art writing or music.
