Why Say It?

I love to write but I wrestle with the notion that enough has been said about everything under the sun. Then I read something that stikes a chord and wakes me up, and I am glad that whoever said it, said it. Like this peom by Kay Ryan:

As though the river were a floor,
we position our table and chairs
upon it,
eat, and have conversation.
As it moves along,
we notice—as
calmly as though dining room paintings were being replaced—the changing scenes
along the shore.
We do know,
we do know this is the Niagara River,
but it is hard to rememberwhat that means.
-------Kay Ryan

I am no Kay Ryan, but good writing gives me courage to keep trying, even though I know "which way the river flows."
