Short Version: There is absolutely no 'Get Rich Quick' in eBooks. The only people getting rich quick are the ones selling you 'Get Rich Quick' courses

Long Version: This might shatter your hopes of getting rich quickly by churning out hastily written books. So please only read if you are willing to face Reality

Let's consider that someone has figured out a way to make a lot of money with minimal effort. The magical '4 hour work week' making the person $100,000 a year or more
Why would someone who has figured out a way to make lots of money from books, while giving just 4 to 8 hours a week, sell it to you?
Why not just hire a few people, who each work 40 hours a week for this magician. As 4 hours a week and minimal effort nets $100,000 a year, each employee would get this person $1 Million a year. 10 employees and he'd be making $10 Million a year

So, this person decided that he would reject
Making $10 Million a year from 10 employees to whom he could pay $500,000 a year total. He rejected a life of luxury
Instead he chose to stop after getting to around $100,000 a year. Took this magical method of making $100,000 a year from just 4 to 8 hours a week. Started selling it for $200 or $400 a pop
He's basically selling away his chance of making $10 Million a year, every single year, for the next 20 years
For What? For $400 an author? He'd have to sell it to at least 25,000 authors to make the same amount of money. And it would be a one time sale. Remember, he's giving away $10 Million a year consistent revenue
