Take wrong turns. Talk to strangers. Open unmarked doors. And if you see a group of people in a field, go find out what they are doing. Do things without always knowing how they'll turn out. You're curious and smart and bored, and all you see is the choice between working hard and slacking off. There are so many adventures that you miss because you're waiting to think of a plan. To find them, look for tiny interesting choices. And remember that you are always making up the future as you go.

I've always thought that one of the the great thing about physics is that you can add more digits to any number and see what happens and nobody can stop you.

Google owns YouTube, and recently, I drew a comic about an idea for a YouTube feature - which they actually took seriously and implemented. So I'm thinking that maybe we'll have a future where Google is 'xkcd.'

I'm not sure why we romanticize 'young love,' or love in general...It just leads to the idea that either your love is pure, perfect and eternal, and you are storybook-compatible in every way with no problems, or you're LYING when you say 'I love you.

Sometimes I mistake this for a universe that cares.

What people don't appreciate, when they picture Terminator-style automatons striding triumphantly across a mountain of human skulls, is how hard it is to keep your footing on something as unstable as a mountain of human skulls. Most humans probably couldn't manage it, and they've had a lifetime of practice at walking without falling over.
