Many people lack confidence these days because of social media. They see others posting perfect pictures and feel like their own lives don't measure up. This constant comparison can make people feel inadequate. Also, negative comments and cyberbullying can really hurt someone's self-esteem. The pressure to look a certain way or have a certain lifestyle online is overwhelming.

High expectations from society are another reason why people lack confidence. There's a lot of pressure to succeed academically and professionally. Parents and peers often expect too much, and the fear of failing can be overwhelming. The competition in various fields is intense, and meeting both personal and societal expectations can be very stressful.

Mental health issues are also a big reason why people lack confidence. Anxiety and depression rates are increasing, and many people don't have access to the mental health resources they need. There's also a stigma around seeking help for mental health, which makes it harder for people to get the support they need. Daily stress and past traumas can also impact confidence levels.

Economic and job insecurity also play a role in why people lack confidence. The uncertainty in job markets and economic conditions makes people worry about their future. Fear of unemployment or not having a stable job can affect their self-worth. Financial instability adds to this pressure, making it hard for people to feel confident about their future career prospects.
