In all Things keep Something in Reserve.

In all Things keep Something in Reserve. ̥Tis a sure means of keeping up your importance. A man should not employ all his capacity and power at once and on every occasion. Even in knowledge there should be a rearguard, so that your resources are doubled. One must always have something to resort to when there is fear of a defeat. The reserve is of more importance than the attacking force: for it is distinguished for valour and reputation. Prudence always sets to work with assurance of safety: in this matter the piquant paradox holds good that the half is more than the whole.
