You have some amazing insights for a "beginning writer"! There is much truth in your assessments, but I would argue with the last point.

Great stories are made. They may start in a flurry of inspiration born of...whatever makes inspiration. But you'll find very few first drafts turned into successful stories. The seeds may be "born" but the final, great work, you're thinking of I guarantee was the result of great effort.

I understand where you get the idea though, reading the freewrites here. I'm in constant amazement of what some of the writers can do in that amount of time (though some of them do say they take more time or edit before posting). Freewrites are born for sure, that's what they're designed to do - free up the mind to create without getting in the way. It's a way to develop writing skills and creativity so those that have been doing it a long time are really good at it. And I bow down to them in their mastery.

Thank you for taking the time to share your thoughts! And welcome to the world of writing!
