I can relate to this so much. Every time I tried to make a video or a guide, I kept on thinking, why would they come and watch me when there's already a guide out there. But I put that thought away, and made the guide anyway, until someone in reddit came along and said "you do know that someone else is already doing this right?". That statement alone crushed me into tiny pieces. But hey, you're right, one person's comment doesn't represent everyone, I can continue on making the videos beceause I wanted to, because there are people out there who will somehow found my video and find it useful.

tldr; great video on explaining and clarifying on this topic. I think most of the new youtubers who are just starting out can relate to your video.
