According to Jeff Goin’s blog ( Hemingway once remarked on his writing process during those early days in Paris as a fledgling writer:

All you have to do is write one true sentence. Write the truest sentence that you know.

So finally I would write one true sentence, and then go on from there. It was easy then

because there was always one true sentence that I knew or had seen or had heard someone say.

Isn’t there at least one true sentence you can say?
