I believe your thinking is sound. Creating original things is one of the fundamental ways to fulfillment, I believe. As long as the goal of your creation is to create for yourself — and yourself only — I believe it can lead to the highest level of achievement. I would caution that creation can be addictive almost as much as consumption. Seeing the number of likes on a video you created go up is extremely addictive and can lead yourself towards overworking to make the next creation. Almost every big youtuber goes through a phase of burnout as they try and chase bigger and bigger hits. Additionally, you are beholden to Youtube not screwing you over which may lead to a situation where YouTube has power over your personal fulfillment.

If you haven’t already I would check out the book “Hooked” as well to learn more about the addictive patterns that are put out there to trap you.
