Most interesting nonfiction that you can finish in a day

Because I’m currently reading James Clavell’s Noble House, I need something to read between bouts of this monstrosity if I’m to keep up with my Goodreads reading challenge.

I’m looking for recommendations that fit this criteria:

1. Nonfiction: self-help and historical nonfiction is okay, but not memoirs

2. Interesting: you found it profound or learned something new from reading it as a layman

3. Easy to get through: uses simple words and not esoteric, eg not Nietzsche

4. Short length: audiobook length is less than 8 hours long

Thanks!
