That dude is smooth. However, I don’t consider being likeable an essential trait. And no amount of self help jargon will convince me otherwise. It’s much better to be good at what you do, and to never give up. That’s it. I wouldn’t advice anyone to ape sociopaths because it doesn’t work unless you are wired that way. Try to be someone you aren’t and ya just end up miserable. And no amount of “success” justifies being miserable.
