In his new book, “In Trees: An Exploration,” writer Robert Moor considers how trees’ lives mirror ours and what their structures can teach about how time and experience shapes us. Moor talks with Design Matters podcast host Debbie Millman.

Moor’s previous book is “On Trails: An Exploration,” which takes a similar perspective on the meaning of trails.

In his interview, Moor talks about his own life as a writer, hiker and world traveler, and how he finds meaning.

“On Trees” and “On Trails” are on my reading list. I’ve been looking for meaning myself lately.
