And so, from hour to hour, we ripe and ripe,
And then, from hour to hour, we rot and rot;
And thereby hangs a tale. [ William Shakespeare ]

Greatness envy not; for thou mak'st thereby
Thyself the worse, and so the distance greater. [ Herbert ]

Great deeds immortal are - they cannot die,
Unscathed by envious blight or withering frost,
They live, and bud, and bloom; and men partake
Still of their freshness, and are strong thereby. [ Aytoun ]

Dare to be true. Nothing can need a lie; A fault, which needs it most, grows two thereby. [ Herbert ]

An old proverb attributes happiness to him who expects little and thereby avoids disappointment. [ Henry D. Chapin ]

They who minister to their neighbors exercise one of the normal human functions, and enter thereby into the joy of a larger life. [ George Hodges ]

We can never be grieved for their miseries who are thoroughly wicked, and have thereby justly called their calamities on themselves. [ Dryden ]

There are certain times in our life when we find ourselves in circumstances, that not only press upon us, but seem to weigh us down altogether. They give us, however, not only the opportunity, but they impose on us the duty of elevating ourselves, and thereby fulfilling the purpose of the Divine Being in our creation. [ Johann Wolfgang von Goethe ]
