13 Things Mentally Strong People Don’t Do

13 Things Mentally Strong People Don’t Do by Amy Morin started as a viral blog post and grew into a bestselling book on emotional resilience. Morin, a psychotherapist who lost her mother and her husband young, writes from real experience, and the framing is the kinds of habits to avoid rather than only the ones to build.

For readers in the personal development category, this is a steady, evidence informed book.
