Great works are performed, not by strength, but by perseverance. - Samuel Johnson

To-morrow's action! Can that hoary wisdom, Borne down with years, still doat upon tomorrow! That fatal mistress of the young, the lazy, The coward, and the fool, condemn'd to lose A useless life in waiting for to-morrow, To gaze with longing eyes upon to-morrow, Till interposing death destroys the prospect Strange! that this general fraud from day to day Should fill the world with wretches undetected. The soldier, labouring through a winter's march, Still sees to-morrow drest in robes of triumph; Still to the lover's long-expecting arms To-morrow brings the visionary bride. But thou, too old to hear another cheat, Learn, that the present hour alone is man's.

A jest breaks no bones.

Courage is a quality so necessary for maintaining virtue that it is always respected, even when it is associated with vice.
