Elements could absolutely help you if you would like to stop screaming at people who don't like something that you do. Or even have the nerve to mock it on the internet. If that seems awesome to you you can safely pass.

Pretty much everyone that writes a book or is a successful poker player has a gigantic ego. Both professions are too difficult to continue in the bad patches unless you really think you can do it.

All that said, I don't like this article and it has not much in common with Elements. Someone famous said something like "The lowest form of human interaction begins with 'Remember when we...' ". I agree.
