Paperback book. Dr. Faith explains the fundamentals of adulting in this handy guide. Spoiler: None of the requirements are about having certain jobs, kids, possessions, and debts, or being totally bored and stressed out and hating your life. This book will not teach you to change your oil or fold fitted sheets. Instead, Dr. Faith offers wisdom from her life experience and counseling practice like, “If it’s not yours, don’t touch it."
