I'm not trying to convince you that self help books are all legit. All I know is my personal experience with the real estate books showed that those were.

People who are religious and survive car accidents claim that miracles are real. They go out and are describe how their ways saved them. Heck they even describe their vision just before the accident.

Do you know what the problem is?

The vast majority of christians that took the exact same steps did not survive to say "hey dude, it didn't work". You only hear the opinion from those who are alive.

same exact thing happens with self-help books.
