Its correctly said by kabeer daas jee that :
" Ati ka bhala na bolna, ati ki bhali na choop. "
" Ati ka bhala na barasna, ati ki bhali na dhoop. "
that just means by suitable examples that excess of everything is bad... One must not do anything in excess...Similarly its with confidence, it is a fact that confidence helps a man in success but it also makes him down in his carrier and life.
I personally suggest that over confidence is the most easy way to get down in life and gives a stable potential in not getting up again with your full pride...
