Wise sayings often fall on barren ground, but a kind word is never thrown away.
One of my favorite little sayings is, 'To avoid criticism, say nothing, do nothing, be nothing.'
Robert M. Gates
A word of kindness is seldom spoken in vain, while witty sayings are as easily lost as the pearls slipping from a broken string.
George Dennison Prentice
The wisdom of the wise and the experience of the ages is preserved into perpetuity by a nation's proverbs, fables, folk sayings and quotations.
