How few there are who have courage enough to own their faults, or resolution enough to mend them.
A word to the wise is enough, and many words won't fill a bushel.
He that's content hath enough.
If better is possible, good is not enough
Those who are content have enough; those that complain, have too much.
He that lives well, is learned enough.
Lost time is never found again, and what we call time enough, always proves little enough.
