self-confidence

what is self-confidence about?
knowing one's strenghts?
knowing the sun-tzu outcomes of a given situation and how to navigate it to one's advantage?
knowing how to dress / speak / carry onself?

what is self-confidence? where did this idea begin?

when we are deeply honest about how unstable we are - our emotions can totally hijack us, our motives are often coloured by greed, fear and lust, the fervour of our efforts wane when the temperature rises... how can we speak of self-confidence ?

what is the point of it?
to feel good about oneself?
to prove something or someone wrong?
to make a difference -- and if so, for what?

When our selves get in the way, things just get murky.
