In the S&R the guys review The Defining Decade by Meg Jay, PhD. The book centers around Jay’s experience as a clinical psychologist seeing people in their 30s and 40s who are hamstrung by having a “lack of vision” in their 20s. This book is meant to provide people in their 20s with some direction around creating that vision (not in a corny way) so that they’re setting themselves up better for their 30s and beyond, instead of playing catch up after derping around for 8 years.
