The 12 Levers by Spencer Greenberg

The 12 Levers: The Complete Psychological Toolkit For Improving Your Life by Spencer Greenberg, PhD & Jeremy Stevenson, PhD — the last self-help book you’ll ever need.

After years of rigorous research — analyzing more than 100 of the most popular self-help books and 23 major forms of therapy — psychologists Spencer Greenberg and Jeremy Stevenson made a striking discovery. Nearly 500 techniques and methods all collapse into just 12 core psychological strategies.

These are the 12 Levers: the fundamental tools that underpin almost every effective approach to personal growth, mental well-being, productivity, and overcoming life’s challenges. In this clear, practical, and evidence-oriented guide, the authors explain each lever in detail and show you exactly how to apply it in real life — step by step.

Whether you’re looking to reduce anxiety, build better habits, improve relationships, increase motivation, or simply understand yourself more clearly, The 12 Levers gives you a complete, organized toolkit instead of another collection of scattered tips. Thoughtfully written and grounded in both science and the best of the self-help tradition, this is a book designed to be used, not just read.

A rational, comprehensive approach to self-improvement for people who want results that actually last.
