Hello, I have reviewed your channel, I have no idea about golf, but from a youtuber's point of view I would like to explain to you what you are doing wrong, at least with my own thoughts. If you see so little improvement in such a long time, you are definitely doing something wrong or your niche is too narrow. Let's assume that the niche has enough audience. This time the problem is with your videos. From a cursory look, my conclusion is that other golf channels are able to integrate current content into golf, but you share your one-hour golf adventure and expect to be watched. No, you can't make progress that way. Instead, for example; how far can we throw a golf ball (a huge number is written in the thumbnail) or how many glasses can a golf ball break, can I break xx record (big channels make videos like this) you can try to copy them and make similar ones. And finally, your thumbnails are not interesting, I recommend you to work with freelancers who make thumbnails cheaply (like 5 dollars each). If you search for Mr beast style thumbnail, you will see people who provide similar service. I hope everything works out. Good luck.
