Self-confidence is an attitude about your skills, values, and abilities that comes from accepting your strengths and weaknesses and trusting yourself. A highly self-confident person would have higher self-esteem and self-respect and thus, would be able to successfully overcome difficulties they face. Whereas, a person with low self-confidence might find it difficult to make simple decisions, have healthy relations, or communicate with new people. Positive affirmations, healthy routines, achieving small goals, etc. are just a few ways of building your confidence and taking care of your mental health.
