Wickedness resides in the very hesitation about an act, even though it be not perpetrated. [ Cicero ]

Hesitation of any kind is a sign of mental decay in the young, of physical weakness in the old. [ Oscar Wilde, The Importance of Being Earnest ]

We should give as we receive, cheerfully, quickly, and without hesitation; for there is no grace in a benefit that sticks to the fingers. [ Seneca ]

Nearly all our powerful men in this age of the world are unbelievers; the best of them in doubt and misery; the plurality in plodding hesitation, doing, as well as they can, what practical work lies ready to their hands. [ John Ruskin ]

His eloquent tongue so well seconds his fertile invention that no one speaks better when suddenly called forth. His attention never languishes; his mind is always before his words; his memory has all its stock so turned into ready money that, without hesitation or delay, it supplies whatever the occasion may require. [ Erasmus ]
