Self-esteem and self-confidence refer to how individuals view themselves and their abilities. Self-esteem is formed based on life experiences and relationships that either build up or diminish one's view of self-worth. High self-esteem involves having a positive opinion of oneself while low self-esteem involves a negative view. Maintaining healthy self-esteem and confidence requires focusing on personal strengths rather than weaknesses, accepting failures, and not comparing oneself to others.
