Honestly, if I could think of something fun to do or teach on youtube and somehow make a lot of money doing it, I'd do it. However, I wouldn't just make a video blog about my life because, as amazing and interesting as my life is, I am 100% sure no one gives two shits about what I do every single day. I'm also not a narcissist.  People like this that start off their channel with just videos of them doing random regular things every day and talking nonstop about nothing intelligent just have less than 0 respect from me. If they are fat, then divide by 0 to see how much respect I have left.
