"Perhaps we write toward what we will become from where we are,” wrote May Sarton in Journal of a Solitude
I’d say it a bit differently—that writing helps us become what we will become. By writing from where we are we are strengthening the ground underneath our feet, stabilizing the shifting sand, so that when we take the next step forward and then the next, our steps will be firm and the ground will not give way as we push against it in raising our foot to proceed. Also the words we write give us little clues to what is coming next, as if our hidden inside knows before we do and will offer only the slightest hint before we discover it in full for ourselves.
