Even if your content is "valuable", it won't get significant views and subscribers and shares unless it's ENTERTAINING. The key to doing that on YouTube is to have a live talking head host that looks good and sounds good. People keep going back to a particular channel because they connect with the personality of the host appearing on camera. Drop the animations and do it live. If you're not smooth/funny/friendly/clever/personable/handsome etc enough on camera, then use a friend or family member that is. Unfortunately, sexist as it is, the optimum host for fast channel growth is a young good-looking woman.
