I read this quote from a site that is one of the best online.

Poetry is not an expression of personality, it is an escape from personality; it not an outpouring of emotion, it is a suppression of emotion–but of of course, only those who have personality and emotions can ever know what it means to want to get away from these things.
–T.S. Eliot
I have to say that I like it. It gives me much to think about as a writer.
