There are no solved problems; there are only problems that are more or less solved.

The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

The master tools of success are invitation, patience, time, gentleness, cooperation, and surrender.

Never tell anyone what you are going to do till you've done it.

When your language is nowhere near Turing-complete, syntactic sugar can be your friend.

The minute I heard my first love story, I started looking for you.
