Depending on your circumstances, your self-esteem will change over time. It's natural to have periods of feeling bad about yourself and periods of feeling fantastic about yourself. However, self-esteem tends to stay in a range that represents how you feel about yourself generally, and it rises modestly with age.
Low self-esteem: You regard your opinions and thoughts less when you have poor or negative self-esteem. You place a premium on your perceived flaws and shortcomings while downplaying your strengths and talents. You think others are more capable or accomplished than you. Positive feedback may be difficult for you to absorb. You may be afraid of failure, which might prevent you from achieving at school or the workplace.
Healthy Self-esteem: When you have a good sense of self-esteem, you have a balanced and fair perception of yourself. For example, you have a strong impression of yourself yet are aware of your weaknesses.
