Nothing.

” I still had no idea what I could do to make a difference. And maybe that’s just it. Maybe what the world needs now is not another mountain or another meadow, as the song goes—or even a new planet—but a willingness to know nothing at all. Drop the sword I’ve held ready to defend a lifetime of accumulated assumptions about what’s wrong with the world and everyone and everything in it. Relinquish the hammer poised to pound the round peg of all the tragedies of the world into the square hole of What I Believe. Wipe the slate clean and dare to hope again.”
