Two factors that directly affect our self-esteem are relationships and behavior. We really cannot distinguish who we are if we don't have relationships with other people. When our relationships with others are both positive and productive, we tend to behave in a positive manner. We feel better about ourselves as well. When it comes to relationships and behavior, a balanced proportion of the two must exist.
Healthy relationships promote healthy behavior, which leads to a healthy and positive self-esteem.
The same comparison can be made between negative relationships and negative behavior. Unhealthy relationships where individuals are mistreated, abused and manipulated result in negative behavior and a negative self-concept. Remember one of the greatest ways to stay mentally and emotionally sound is to appreciate, respect and love yourself. No one is perfect, accept your limits. Learn to cope with difficult experiences.
