A quote
Great generals, when they see that their men are mutinous, check them by some sort of labour or keep them busy with small forays. The much occupied man has no time for wantonness, and it is an obvious commonplace that the evils of leisure can be shaken off by hard work. Although people may often have thought that I sought seclusion because I was disgusted with politics and regretted my hapless and thankless position, yet, in the retreat to which apprehension and weariness have driven me, my ambition sometimes develops afresh. For it is not because my ambition was rooted out that it has abated, but because it was wearied or perhaps even put out of temper by the failure of its plans.
