Self-esteem and self-compassion
Psychologist Morris Rosenberg defined self-esteem as the overall attitude we have toward ourselves. Research by Kristin Neff adds a key idea: self-compassion, treating yourself as you would a good friend, is more stable than self-esteem based on achievements or comparisons.
Knowing what sabotages your self-esteem lets you work on it directly: questioning your inner critic, limiting comparisons, learning to say no or relating differently to your body.
