self-worth
The feeling that you are valuable and deserve respect.
Self-worth is the sense that you have value as a person, independent of what you accomplish or what others think of you. It's recognizing that you matter simply because you exist, not because you got an A on your math test or scored the winning goal.
Someone with strong self-worth believes they deserve kindness and respect, even when they make mistakes or fail at something. They can feel disappointed about a bad grade without thinking they are bad. They can lose a game without feeling worthless. They understand that their value doesn't go up and down like a scoreboard.
Self-worth is different from confidence, which is believing you can do something well. You might lack confidence in your ability to solve a difficult puzzle while still maintaining your self-worth: you're valuable whether you solve it or not. Similarly, arrogance (thinking you're better than others) isn't the same as self-worth, which means recognizing your own value without needing to put others down.
Building self-worth often comes from treating yourself with the same kindness you'd show a good friend. When you make a mistake, you can acknowledge it and try to do better without telling yourself cruel things you'd never say to someone else. Real self-worth helps you handle both success and failure with grace, knowing that neither one changes who you fundamentally are.
