Self-confidence is the belief in oneself and abilities, it describes an internal state made up of what we think and feel about ourselves. This state is changeable according to the situation we are currently in and our responses to events going on around us. It is not unusual to feel quite confident in some circumstances and less confident in others. It is also influenced by past events and how we remember them; recalling a former success has a very different outcome in terms of our confidence levels than thinking about an occasion when we failed. Confidence and self-esteem are terms which are often used interchangeably, but although there is over-lap perhaps there are also subtle differences. Self-confidence can refer to how we feel about ourselves and our abilities whereas self-esteem refers directly to whether or not we appreciate and value ourselves.
