I Will Teach You To Be Rich – Ramit Sethi

Rating: 9/10 If you're young and live in the US, it's a 10/10. Great starter book on personal finance. Teaches a clever system to automate saving and guilt free spending. Has detailed recommendations of banks accounts and credit cards (check his website for updates before opening any). It's sequenced as a six-weeks-to-do-list so you take action that gets you 85% there, with options for optimizing later (becoming more of an expert).

Healing Back Pain: The Mind-Body Connection – John E Sarno

Rating: 10/10. If you're conscientious, hard working, responsible, perfectionist, ambitious, it's likely that your brain uses back pain (or other symptoms) to avoid experiencing powerful negative emotions like anger, anxiety and low self-esteem. Worse case scenario, if this book is a placebo, then it's cheaper than chiropractor/acupuncture/massage/physical therapy/surgery.
