Do not underestimate good, thinking it will not affect you. Dripping water can fill a pitcher. drop by drop; one who is wise is filled with good, even if it accumulates little by little.
The kingdom of heaven is like a mustard seed that someone took and sowed in his field; it is the smallest of all the seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches.
