True. Families, peers, media, and school all influence one's level of self-esteem.

Self-esteem is a reflection of how one sees and values himself or herself. Views contributed by outside environment regarding one's self worth will influence one's level of self-esteem.

For example:
You grew up in a family who supports you in achieving your goals and who believes that you are capable in achieving your goal. You hold yourself in high-esteem because you see your high-value in the family.
You go to school and people hate you and make fun of you , your level of self-esteem will decrease because the people in school do not value you as much as you are valued in you family.
These are just some examples of how outside factors influence one's level of self-esteem.
