Developing robust self confidence can seem to be such an immensely personal thing; a quality acquired only by trial and error, something requiring lots of introspection and self-analysis.
If this were completely true, then precious few people would ever really be confident. Yet the fact is that many people are - regardless of whether they are capable of real introspection or profound self-analysis.
In reality, feeling good about ourself is directly related to self-esteem or how much we believe we are worthy of respect, from ourselves as well as from others. A perceived lack of respect prevents us from feeling we are capable of trying new things, let alone accomplishing or excelling at them.
