The casino story from somewhere i adapted- You go to a casino where rich folks have loads of chips and poor folks have much lesser. rich folks bet with loads of chips and when they win they get loads of chips more! if ever unfortunately they lose, they bet as much again, and they will not go on losing forever. (: hence they will always have load load loads of chips, YAY! and de other corner yu see e poor folks miserably wif mini chip amounts.when they lose, they boohoohoo. they win, they get little chips back. and how long before they reach many chips? most problably they will just die away with no chips very soon. and then yu'll seee the rich pple multiplying their chips. and they can even spare some tothe poor folks. and when de poorer ones return the rich their chips, the rich get richer!
the story's moral. your confidence level are like the chips yu own. yu have to start wif MANY chips. build on it. and get more more more more more chips. get mountains of chips. be confident(: and help others along too to regain their confidence, hence boosting your own.
dun u tink this is a so-nice-until-cannot-use-meer-words-to-describe- analogy =D
