Weigh not so much what men assert, as what they prove. Truth is simple and naked, and needs not invention to apparel her comeliness.
Philip SidneyAs in labor, the more one doth exercise, the more one is enabled to do, strength growing upon work; so with the use of suffering, men's minds get the habit of suffering, and all fears and terrors are not to them but as a summons to battle, whereof they know beforehand they shall come off victorious.
Philip Sidney
