Although there is a lot of truth here, the one thing that is not on here is the simple fact that a diamond is still a diamond even if it cannot be found. While personally, I will never argue that my content is great or even deserving, I have seen great content from awesome channels that have almost no views or subs. It is not for lack of good content that some channels do not get seen, but because there are other powers at play other than the pure organics of viewer choice. These powers have agendas they want to promote and if your content, great as it may be, is not part of that agenda, it may get buried under the content that the powers want people to see so that it is never seen. This is a reality of an internet that is under the control of a handful of monopolistic companies that control all the funding and they have a stranglehold on the flow of information.
With that said, all one can do is try, try, and try again. Keep improving and adjusting as much as possible, but hopefully, never sell your soul in the process.
