The 12 Levers

The 12 Levers compiles and analyzes advice from over 100 self-improvement books and 20 therapeutic approaches to identify a core set of twelve psychological strategies for change.

Co-authors Spencer Greenberg and Jeremy Stevenson combine public-facing tools and clinical experience to present practical exercises and diagnostics for problems like anxiety, rumination, and habits.

The book emphasizes understanding causes, steering attention and thoughts, and planning actionable experiments to iteratively improve one’s life.

It draws on cognitive behavioral therapy, REBT, exposure techniques, and attention training to offer a structured toolkit rather than a single quick fix.

Intended as a meta-guide, it aims to give readers an accessible, evidence-informed set of interventions to apply across a range of psychological challenges.
