Lost in Thought and the Second Mountain by Jason Hits

The book is called lost in thought by zena hits. The tag line on it, is, the hidden pleasures of an intellectual. After that, i read the second mountain by david brooks. Both lost in thought and the second mountain were late additions to the reading list. They were not part of the original list. So going on from there, a the next series of books were all the books that russ roberts has written.
