I think writing freely without structure is, in a way, more beneficial than writing for a prompt. Sure there are times when structure can be helpful and it is a great way for a young writer, but writing freely (in my own opinion) is what makes people fall in love with writing. It wasn't until I was in collegiate creative writing classes that I realized the passion I had for it. I think often about how much I would have enjoyed using writing throughout my childhood, but I wasn't really presented with the opportunity to develop a love for it.
That is really what the title of the article is all about. Self revelation. "A surprising and previously unknown fact." According to Webster, this is the definition of revelation. This really makes the title, Writing as Self Finding. That plays exactly into my own view of why writing is so great!
