Sorry to hear you had such a bad experience with Clickbank. Refunded 5 weeks later? That’s pretty extreme! I could not find any info on CB on whether gravity takes into account refund rates, but from other blogs, I read that NO, it doesn’t take it into account. The Earned/Sale category however does take this into account, which is why the average $ earned per sale will sometimes be different from the actual commission you make.
You’ll also need time for review, feedback, instructions, and progress checks. There’s a lot to do besides actually teaching the session’s content! For example, it’s often a good idea to have clients share their “wins” and their struggles each session, to commiserate on their progress and stimulate ideas for improvement. You should also go over what was learned in the last session, and see how clients applied it. These things contextualize the content, and create continuity and accountability over the whole course of the “package.”
If you just had a website up with your picture that says “I'm a coach, hire me!”, people will say “Who cares?” People are much more likely to hire and work with someone if they've already provided value to them in advance (through your content) and they've established a relationship with you (through your content). If you just have a coaching website that offers coaching – nobody cares because nobody knows anything about you, haven't received any value from you, nor do they have any relationship with you whatsoever.
If you really wanted to make the list even more exhaustive, you could also discuss the various biological money-making methods (e.g., sperm donation, egg donation, etc.) and/or go into the more technical (e.g., hosting websites on one’s own server, building computers for others, etc.). Also, you could potentially explore those well-known money-making ventures, such as trading on the stock market, which are seemingly difficult to enter into by their apparent complexity by listing various online instructional tools which assist novices looking to get involved in them (e.g., Investopedia’s online simulator to prepare for buying/selling stocks). Sometimes those methods of making money which appear to be the most difficult are, in fact, relatively simple once you understand the underlying conceptual framework – many people just don’t realize this.

Not everyone is able to do this, being an affiliate is similar to being a marketer. There are people who can do meanwhile others cannot, Clickbank is not a means of making money, but more of a base to make money, acts as intermediary between vendors, affiliates and customers. You will work for yourself, find customers who would purchase the products you advertise but do nothing for Clickbank.
