Whatever you're meant to do, do it now. The conditions are always impossible

I don't think the human race will survive the next 1,000 years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars

Death happens but once, yet we feel it every moment of our lives; it is worse to dread it than to suffer it

Weird doors open. People fall into things.
