Is self esteem and self efficacy the same thing?

Albert Bandura defined self-efficacy as "beliefs in one's capabilities to organize and execute the courses of action required to produce given attainments". In other Words, its a kind of situation-specific self confidence. It's believing you can do specific thing.

Self esteem is your opinion of yourself. Having high self-esteem could help you be more confident, thus giving you self-efficacy in a certain task.
