Fortune is like the market; where many times if you can stay a little, the price will fall. Again, it is sometimes like Sibylla's offer; which at first, offereth the commodity at full, then consumeth part and part, and still holdeth up the price. For occasion (as it is in the common verse) turneth a bald noddle, after she hath presented her locks in front, and no hold taken or at least turneth the handle of the bottle, first to be received, and after the belly, which is hard to clasp. There is surely no greater wisdom, than well to time the beginnings, and onsets, of things. Dangers are no more light, if they once seem light; and more dangers have deceived men, than forced them. Nay, it were better, to meet some dangers half way, though they come nothing near, than to keep too long a watch upon their approaches; for if a man watch too long, it is odds he will fall asleep. On the other side, to be deceived with too long shadows (as some have been, when the moon was low, and shone on their enemies' back), and so to shoot off before the time; or to teach dangers to come on, by over early buckling towards them; is another extreme. The ripeness, or unripeness, of the occasion (as we said) must ever be well weighed; and generally it is good, to commit the beginnings of an great actions to Argus, with his hundred eyes, and the ends to Briareus, with his hundred hands; first to watch, and then to speed. For the helmet of Pluto, which maketh the politic man go invisible, is secrecy in the counsel, and celerity in the execution. For when things are once come to the execution, there is no secrecy, comparable to celerity; like the motion of a bullet in the air, which flieth so swift, as it outruns the eye.
