Dhammapada verses 122 and 123

122. Think not lightly of good, saying, “It will not come to me.” Drop by drop is the water pot filled. Likewise, the wise man, gathering it little by little, fills himself with good.

123. Just as a trader with a small escort and great wealth would avoid a perilous route, or just as one desiring to live avoids poison, even so should one shun evil.
