A fool who recognises his own ignorance is thereby in fact a wise man, but a fool who considers himself wise - that is what one really calls a fool.
Gautama BuddhaDo not overlook tiny good actions, thinking they are of no benefit; even tiny drops of water in the end will fill a huge vessel. Do not overlook negative actions merely because they are small; however small a spark may be, it can burn down a haystack as big as a mountain.
Gautama Buddha
