I just re-discovered this famous quote from Ernest Hemingway’s preface to The Short Stories…
In going where you have to go, and doing what you have to do, and seeing what you have to see, you dull and blunt the instrument you write with. But I would rather have it bent and dull and know I had to put it on the grindstone again and hammer it into shape and put a whetstone to it, and know that I had something to write about, than to have it bright and shining and nothing to say, or smooth and well-oiled in the closet, but unused.
