A prince never lacks legitimate reasons to break his promise.
A promise made is a debt unpaid.
All promise outruns performance.
Better break your word than do worse in keeping it.
Between today and tomorrow are graves, and between promising and fulfilling are chasms.
But I have promises to keep, and miles to go before I sleep, and miles to go before I sleep.
Civilization rests on a set of promises; if the promises are broken too often, the civilization dies, no matter how rich it may be, or how mechanically clever. Hope and faith depend on the promises; if hope and faith go, everything goes.
Eggs and oaths are easily broken.
Everyone's a millionaire where promises are concerned.
God never made a promise that was too good to be true.
Half the promises people say were never kept, were never made.
He is poor indeed that can promise nothing.
He loses his thanks who promises and delays.
If you wish to be success in the world, promise everything, deliver nothing.
In the midst of great joy, do not promise anyone anything. In the midst of great anger, do not answer anyone's letter.
It is not the oath that makes us believe the man, but the man the oath.
It is useless to hold a person to anything he says while he is in love, drunk, or running for office.
Never take a solemn oath. People think you mean it.
No pillows so soft as God's Promise.
Nothing weights lighter than a promise.
