I'm Rufus Griskem, and this is the next big idea.

Today, how constraints make us better. In the mid-1950s, the head of Houghton's Education Division,

challenged Theodore Geisel, better known as Dr. Seuss, to write a children's book using no more than

225 words from a list of first grade vocabulary. There are no adjectives, Gaisel complained

to his wife. It seemed like an impossible task. But he gave it a try. He decided to take the first

two rhyming words on the list and make a book.

And the first two rhyming words, cat and hat. A few years later, Bennett's surf, the co-founder of Random House,

bet Geisel 50 bucks that he couldn't write a children's book using only 50 words this time.

So again, he's frustrated, but he takes up the challenge and writes green eggs and ham,

where even more has to rely on this, like, rollicking rhythm because he has no, no flexibility

with the vocabulary.

I am Sam.

Sam, I am.

That's Sam I am.

That's Sam I am.

I do not like that Sam I am.

Without that bet, without what appears to be a totally arbitrary limitation in the number of

words Dr. Seuss could use, we wouldn't have perhaps the two most famous children's books in history.

This is one of countless examples of the essential

role constraints play in generating creativity and innovation presented in David Epstein's latest book

Inside the Box, which we at the Next Big Idea Club have selected as the most important new book

for the spring of 2026.
