The document discusses the negative effects of low self-esteem. People with low self-esteem often do not fulfill their potential as they may not pursue goals or education. They are also more likely to accept poor treatment from others. Common causes of low self-esteem include uninvolved parenting, abuse, negative thought patterns, and making bad choices in the past. Low self-esteem can negatively impact one's work life by causing stress, lack of motivation, difficulty with public speaking or presentations, and warped social relationships. It can also lead to an aversion to criticism, missed opportunities due to fear of taking risks, difficulties with decision making, and ultimately, failure in life.
