The Master-Key to Riches: The World-Famous Philosophy of Personal Achievement Based on the Andrew Carnegie Formula for Money-Making by Napoleon Hill

4.0

Yes, repetition is the key to forming new habits, but I feel unnecessarily beaten about the head to the point where I'm wondering if MK-Ultra surreptitiously infiltrated my brain.

Napoleon Hill is a God (I think MK-Ultra made me say that) and this book goes into more detail than Think and Grow Rich, but if you've read the latter then that's probably enough--your get the gist.
