We must.

In the following excerpt, L’Engle shows her resolution in spite of editors‘ negative reactions to an earlier novel.

The blow felt like “an obvious sign from heaven,” she wrote, “an unmistakable command: Stop this foolishness and learn to make cherry pie.” L’Engle covered her typewriter, vowed to abandon it forever, and walked around the room, sobbing.

Then, suddenly, she stopped crying. In her despair, she realized she was already considering turning this moment into another book—one about failure. She would write. She had to write. Even if she never had another work published. “It was not up to me to say I would stop, because I could not,” she wrote. And the novel that lay around the corner was about something far greater than failure.

It is the same for me. I must write. I have been rejected countless times and I‘ve learned to improve my writing with each story. I am happy because I put pen to paper while I am on my morning commute to work.

I can’t imagine doing anything else that satisfies, challenges, makes me want to create, express joy, sadness, or . . . . live.
