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 read comics and I did science, and never really put them together until I accidentally found myself in the middle of one.

You don't become great by trying to be great. You become great by wanting to do something, and then doing it so hard that you become great in the process.

I never trust anyone who's more excited about success than about doing the thing they want to be successful at.

Space is about 100 kilometers away. That’s far away—I wouldn’t want to climb a ladder to get there—but it isn’t that far away. If you’re in Sacramento, Seattle, Canberra, Kolkata, Hyderabad, Phnom Penh, Cairo, Beijing, central Japan, central Sri Lanka, or Portland, space is closer than the sea.

I think the comic that's gotten me the most feedback is actually the one about the stoplights. Noticing when the stoplights are in sync, or calculating the length of your strides between floor tiles - normal people notice that kind of stuff, but a certain kind of person will do some calculations.

Sometimes I mistake this for a universe that cares.
