My weaknesses... I wish I could come up with something. I'd probably have the same pause if you asked me what my strengths are. Maybe they're the same thing.
It will not be we who reach Alpha Centauri, and the other nearby stars. It will be a species very like us - but with more of our strengths and fewer of our weaknesses.
I do not love thee less for what is done,
And cannot be undone. Thy very weakness
Hath brought thee nearer to me, and henceforth
My love will have a sense of pity in it,
Making it less a worship than before.
