Patrick RothfussRemember this son, if you forget everything else. A poet is a musician who can't sing. Words have to find a man's mind before they can touch his heart. And, some men's minds are woeful small targets. Music touches their hearts directly, no matter how small or stubborn the mind of the man who listens.
