I think that what most surprises anybody who goes into politics from even a modestly cerebral background is the vulgarity of much of the cut and thrust of politics.
Take out another notebook, pick up another pen, and just write, just write, just write. In the middle of the world, make one positive step. In the center of chaos, make one definitive act. Just write. Say yes, stay alive, be awake. Just write. Just write. Just write.
