Who can become a YouTuber?

Today we all have smartphone with video cameras and can record a video in whatever situation. Many people take advantage of this easy technology and publish their videos on YouTube also hoping to make some extra $$$ on this. But what are real factors that will make you a successful youtuber? I think that you have to upload 1. Or something very new and very interesting; 2. Or something cute (kitties or puppies playing); 3. Or something very stupid. In fact, one of the most popular and rich YouTubers, PewDiePie, make extremely stupid videos, which I personally, do not have patience to watch :). So here comes my main conclusion:  in order to be successful on YouTube, you need to make something really , really stupid! Most stupid people don't have better things to do other than watch video's. They won't probably watch a video corse of European History, but PewDiePie's channel for sure!  Therefore, if you don't tend to think of yourself as of a stupid person, the best you can do to have many views is to come up with something very new and exciting that others just don't show OR .... just film your kitty playing :)
