Most of you ass clowns become fanatics for useless causes. You are not gonna save the world. You are not gonna save the animals. You are not gonna save people from guns. You are not gonna stop bullying. Most of you are not gonna do shit. The one thing I guarantee is that if you become a fanatic for your own VIGOROUSITY you will see a change in your life. Too bad many of you do not wanna be accountable and waste their lives on jive and gibberish. Who cares go unfuck yourself and Get Vigorous.
