Book excerpt: People of all ages, backgrounds, and circumstances struggle with low self-esteem. This long-awaited, fully revised second edition of the best-selling The Self-Esteem Workbook includes up-to-date information on brain plasticity, and new chapters on forgiveness, mindfulness, and cultivating lovingkindness and compassion. If your self-esteem is based solely on performance—if you view yourself as someone who’s worthy only when you’re performing well or acknowledged as doing a good job—the way you feel about yourself will always depend on external factors. Your self-esteem affects everything you do, so if you feel unworthy or your confidence is shaped by others, it can be a huge problem. With this second edition of The Self-Esteem Workbook, you’ll learn to see yourself through loving eyes by realizing that you are inherently worthy, and that comparison-based self-criticism is not a true measure of your value. In addition to new chapters on cultivating compassion, forgiveness, and unconditional love for yourself and others—all of which improve self-esteem—you’ll find cutting-edge information on brain plasticity and how sleep, exercise, and nutrition affect your self-esteem. Developing and maintaining healthy self-esteem is key for living a happy life, and with the new research and exercises you’ll find in this updated best-selling workbook, you’ll be ready to start feeling good about yourself and finally be the best that you can be.
