Loved this post on Shauna Niequist's blog - look at all the comments for a plethora of her reader's favorite quotes. This one slayed me though...
“One of the few things I know about writing is this: spend it all. Shoot it, play it, lose it, all, right away, every time. Do not hoard what seems good for a later place in the book, or for another book; give it, give it all, give it now.
The impulse to save something good for a better place later is the signal to spend it now. Something more will arise for later, something better. These things will fill from behind, from beneath, like water. Similarly, the impulse to keep to yourself what you have learned is not only shameful, it is destructive. Anything you do not give freely and abundantly becomes lost to you. You open your safe and find ashes.” ~ Annie Dillard
Now, go and read Dillard's Pilgrim at Tinker Creek and thank me later.
