• Clutter impacts mental health: Chaos stifles focus and creativity.

Rubin’s approach avoids extreme minimalism, focusing instead on “good enough” order that aligns with personal preferences.

The book also ties organization to broader happiness principles from her previous work.

Like The Happiness Project and Better Than Before, this book blends behavioral science with personal experimentation. It extends her focus on habits and self-knowledge, encouraging readers to identify what works uniquely for them—a hallmark of Rubin’s philosophy.
