Excellent story, Fasiha. I was thinking about this topic just yesterday. Often, for me, getting started is most of the battle. Once started, writing from the heart is also difficult. It often makes me feel vulnerable.
Hemingway had a style of writing that I admire. When it comes to writing from the heart, he said, “There's nothing to writing. All you do is sit down at a typewriter and open a vein.”
