Again, post-hoc bias.

The results happen (e.g someone becomes succesful) and then they tell you how they did it—most usually write a book about it because they believe what they did worked.

It doesn't work like that. Imagine how many people immitated these techniques and ended up nowhere. it' s a sham

those people might have done the same thing but because of bad luck they didn't make it this they didn't write a book how "not to do it"

it' classic marketing technique. i can't believe how many people fall for it...
