It does not take a great supernatural heroine or magical hero to save the world.
We all save it every day, and we all destroy it -- in our own small ways -- by every choice we make and every tiniest action resulting from that choice.
The next time you feel useless and impotent, remember what you are in fact doing in this very moment. And then observe your tiny, seemingly meaningless acts and choices coalesce and cascade together into a powerful positive whole.
The world -- if it could -- will thank you for it.
And if it does not... well, a true heroine or hero does not require it.
