First, you haven't read enough or you'd know that "alpha" isn't something you become. You either do alpha shit, or you don't. I know of plenty of short men that exhibit alpha behavior--It has nothing to do with anything.

You need to read more TRP theory bruh.

Also 5'8 is not short. Height only presumes status and value upon people. Once they talk to you, they find out fast whether their perceived value judgements are accurate. However, if you're thin as a twig and tall, it means nothing from what I'm told. People see a twig tall guy as weak and goofy looking. At 5'8 you can keep on more weight and look bigger, faster, than a tall guy that's thin. You could spend all day arguing the benefits of being tall or short. It's a waste of time. Seeing as you have a finite amount of energy throughout your life and day, you should spend your time on more constructive shit.
