I often daydream about how the world can be a better place, but I've given up on activism and politics in the traditional sense. I'm somewhat idealistic, somewhat cynical, but ultimately not preachy. I may call out your opinion/comment if it's reactionary, classist, racist, right-wing, close-minded, etc., but I don't take things too seriously. I do tend to look for some degree of compatibility in values with who I befriend and become close to though.
For the most part, my world changing ambitions are on the backburner. Until social movements are relevant, I want to make my mark through education. The quote on top is how I remind myself that after all, I'm only one person.
Conversely, I have an incredibly unserious side as well. I like playing video games and watching stuff on Netflix to cool off, and since going to university I've become capable of being extroverted too.
