Why You Act the Way You Do

Why You Act the Way You Do

by Tim LaHaye

Understand your personality. Strengthen your relationships. Live with purpose.

In Why You Act the Way You Do, Dr. Tim LaHaye introduces a practical and easy-to-understand framework for personality using the four classic temperaments: Sanguine, Choleric, Melancholic, and Phlegmatic. By helping you identify your dominant traits and temperament blends, this book reveals why you think, react, and relate the way you do.

More than a personality guide, this faith-based classic shows how greater self-awareness can lead to personal growth, emotional balance, and stronger relationships. LaHaye explains how understanding your temperament can help you recognize your strengths, manage your weaknesses, and develop healthier habits in both your personal and professional life.

Through practical insights grounded in Christian principles, the book explores how personality affects career success, emotional wellbeing, marriage, and spiritual growth. Whether you’re seeking clarity about yourself, improving communication with others, or discovering your God-given gifts, this book offers a thoughtful roadmap for growth and maturity.

Discover yourself better—and learn how to become your best self.
