I know you guys recommend not talking about TRP whatsoever because of damages to personal reputations, but my friend has suddenly had a desire to lose 20kg, take up photography and started listen to the audiobook for 'How To Get Anyone To Do Anything.'

I've introduced him to How To Win Friends and Influence People, but not 48 Laws of Power because I don't know how far down the rabbit hole he is ready.
