Low Self-Esteem and Self-Confidence
Self-esteem is a subjective sense of how much we value ourselves and our beliefs. It is linked with self-confidence because when we have good self-esteem, we tend to feel more confident.
The flip side of this is low self-esteem, which is when you have low self-worth and a low opinion of yourself. It is more than just being self-critical and encompasses factors of not feeling good enough.
Having good self-esteem is important so you have the confidence to achieve the things you want in life.
