It's tempting to just write a comic called 'Everyone Mail Randall Munroe Twenty Bucks' - maybe it would work, and I could just close down the 'xkcd' store and sit on a beach and draw pictures and make snarky Reddit posts for the rest of my life.

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.

Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.

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.

News networks giving a greater voice to viewers because the social web is so popular are like a chef on the Titanic who, seeing the looming iceberg and fleeing customers, figures ice is the future and starts making snow cones.

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.

Our brains have just one scale, and we resize our experiences to fit.
