Communication affects every interaction. Communication affects every relationship, especially those with our families, people we love, friends and co-workers. Our level of skill in communicating either enhances or diminishes each interaction. Improved communication opens channels between students and educators, and this improves performance. Your self-esteem either limits you, or propels you beyond what others perceive as boundaries.
People aspire to their level of hope.
When a student's self-esteem is low, his interest and willingness to learn is also low. This tends to cloud his abilities. When self-esteem is high and people feel they are of value and worthy of respect, their quality of life tends to be high and they accomplish more. When self-esteem is low, perceived limits are low and we can fall vulnerable to many of society's ills. We are all vulnerable when we are down.
