Yeah i just gave up on trying to save the world, it's really nothing more than a hollywood trope, it's nonsense. Best you can do is make your little corner of the universe better, help your neighbors etc. Even someone like MLK jr, what did they do to help anyone in europe asia africa south america?
Like what could i do to help anyone on a different continent? Donate money via the Internet to some NGO and hope it's not a scam because i really would have zero control over what happens to the money after i click send.
So i do what i can instead, volunteer at the local high school, donate clothes to the local homeless shelter, do stuff where i can see the impact. Vote in local elections (MUCH more important than voting in national elections), help my elderly neighbor bring in groceries etc etc. Idk what else can we do??
