Real talk, aside from walking into a voting booth every few years, what actual real world effort have you put into changing the world and system?
Because I'm gonna be honest, I hear this defeatist sentiment a lot, and it's almost always from people taking other's word on the matter, not from the people who are out on the ground enacting real change every day.
Change isn't impossible, it's just hard. You just have to ask yourself if you care enough to put in the effort or if you're just waiting for revolution because it's the easy answer.
