Tim Urban's TED talk:

Here’s a little puzzle. Why did Charles Darwin wait a couple decades between first observations on evolution, and publishing his revolutionary book “On the Origin of Species”? He dabbled with a variety of other ideas and experiments, certainly, but he also spent a lot of time obsessing over barnacles. He even later admitted “I doubt whether the work was worth the consumption of so much time.” A new book puts Darwin among a group of august procrastinators, and asks a surprising question: Can procrastination can lead to startling innovation?

This hour, On Point: Delay, brilliance, and procrastination.
