I think must people get discouraged before they even start, just simply by looking at the statistics. I think YouTube defiantly needs to fix their search engine in some ways to help the little guys out, but thats easier said than done. I would say some of the best youtubers are made from the hard work they had to put in to get to the top. It's why we look up to them and structure our videos to match theirs. I think that's truly the key to being successful. Those that already are successful, are there for a reason, it's just a matter of knowing how they did it and imitating that. That itself is essential, along with SEO, learn that and you have learned the YouTube algorithm.
