Updates & Errata

Mistakes happen. This page is for updates about the text in The First 20 Hours. I work to have 99.9999% accuracy in my manuscripts - the “gold standard” of reliability many engineering disciplines (like aircraft design) use to measure quality.

In a 70,000 word manuscript, that’s seven errors. If readers find errors in the manuscript, I’ll post them here, and they’ll be corrected in the next printing.

Errata (first printing)

Page 1. “Every day, I come up [with]” - missing “with.”

Page 23. Jackson Pollack should be Jackson Pollock.

Page 94. Production editor error: gem update–system should be gem update --system.
