There have a word, "Such is the result of such action", it's indicate to faith on our ability and competence, and hardly believe this, if i worked anything hardly and with confidence the result will be positive. One's ability depends on his competence and competence make him over confident to get a good result for his work. It's a very positive thinking that be faith on our ability and competence, because it is the only way that we can success in life.

Thank you all
