So said Julio Cortázar:

Creo que todos tenemos un poco de esa bella locura que nos mantiene andando cuando todo alrededor es tan insanamente cuerdo.

In other words:

I think we all have a little bit of that beautiful madness that keeps us walking [moving forward]  when everything around us is so insanely sane.

Exactly, Mr. Cortázar. Exactly.

My favorite Cortázar story: an imperfect but decent English version, and the original Spanish.
