I respectfully disagree with most of your pointers.
1. OBS is free and more functional.
2. You don't have to buy professional mics to make good content, it's just an added luxury.
3. You don't have to always talk, that'd be annoying. Don't do what you don't want to do. Besides, plenty of good YouTubers aren't like PewDiePie or some other YouTuber that acts like they are on drugs.
4. Uploading on a regular basis isn't a major concern for small YouTubers that don't make money or atleast very little. The only reason you should upload on a regular basis is if you are: getting paid; want to upload often; or believe that it would bring in more subscribers to watch your videos (which isn't something that happens over-night). Quality > Quantity.
5. This guy really is all about putting on a fake smile. Don't sound like you hate the world and don't sound like you want everyone to know they should be concerned when they see you alone with them, just liven up when making a commentary. It doesn't have to be forced or too energetic and it really shouldn't be.
6. I agree with #6 and I also believe that some of his pointers counter fun and favor more of just overly hard work.
Here's some of my pointers (should you disagree, go ahead and disagree because everyone has a different mentality from someone else):
7. Reach out and collaborate with other YouTubers. There's a reason why some YouTubers are as popular as they are now. That reason may be luck or collaborating with other YouTubers that also have an audience. YouTube is not friendly to small channels, so the only way to get recognition is to promote yourself on forums like PMC's video's subforum or give the person(s) you're collaborating with's fanbase what you have to offer as a YouTuber. Collaborating (in this case) = Playing games and commentating with other YouTubers.
8. Don't record when you aren't feeling like it. If I stumble across your channel and I find a video of you where you were playing a game and was incredibly boring, then I would not give one of your videos another click. Even if you have better videos on your channel. Don't treat it like an average workday. If you want to make a career from YouTube (or maybe Twitch), then you should be treating it like you are the boss and you make the hours.
9. Grammar is important. Scenario: You find a video titled "minecraft episdoe 5 with ZzYwertyZz"; what do you think when you see that video? I know what I think; I'm not watching that video. If they don't put in the effort to be professional, then they aren't professional. "Minecraft Ep. 05 w/ ZzYwertyZz" is something I would consider watching.
10. Experiment with different styles to see what fits you and your audience's (and potential audience's) satisfaction. If your current style works, then don't depart to much from that. I suggest trying it on a video or two and ask how they feel about the new style you are trying out.
Good luck on however you plan to go about your YouTube channel. Whether that may be a hopeful career or just a fun hobby, everyone has the chance to get what they want and should not have to compromise.
