Self-esteem is how you think about yourself and the beliefs you have about yourself. These might be beliefs about how you look, your personality, your work, your future or how you get on with people.

If you have healthy self-esteem you will generally think positively about yourself, notice things you do well and feel good about yourself. You will still experience difficult times in life, and have worries, but you will be more confident and able to deal with these.

If you have low self-esteem you might generally think negatively about yourself and focus on weaknesses or mistakes you have made, you might find it hard to see the good parts about yourself that other people see.

It can be difficult to understand why someone has low self-esteem - you might see them as confident, outgoing, kind, chatty, pretty, interesting, funny, honest - but it can be hard to see yourself how other people see you. If you have low self-esteem it can seem impossible to believe anything positive about yourself - even if somebody else points it out. This video "You're more beautiful than you think" shows how sometimes what you see can be very different from what someone else sees.

There are a few things  you can do to try and build up your self-esteem - you can read more about this on the Mind page.
