If you know the course and are not ready, it is useless.

I didn't see the course until today.

It is better, of course, to know useless things than to know nothing.

Why I came here, I know not; where I shall go it is useless to inquire -- in the midst of myriads of the living and the dead worlds, stars, systems, infinity, why should I be anxious about an atom?

We're not going to be ready until January,

It's going to happen again. And we're not ready for it, as you can see by Katrina. ... We're going to have another Sept. 11; it's inevitable.
