It's a very good book, I haven't read it since I was a kid.

The title is unfortunate, and doesn't really reflect the book IMO.

It sounds like a seedy way to manipulate people and get what you want.

I think a more appropriate title would be "Treat people with kindness and decency and your life will probably be better as a result." Or "A manual for interacting with fellow humans".

I need to reread it actually.

Edit: It has been decades since I read it, but that is my recollection of it at least.
