Internet has evolved in a way that we have so much good content like this for free... You probably learned all you talked about in your paid video for free.
We have toons of amazing videos and books for free.
This. Also, while I'm not saying that what you've written is bad(haven't read it obviously), but what are the chances that what you've made is actually superior to the huge number of free articles and guides we have right now? Very unlikely as far as I know. If your content is good, you might actually earn more by making it free and just adding relevant and reputable referral links to your website.
