你杀死了你的敌人，而当他死了，你的职业便不复存在，你从胜利中获得的满足感也会很快消退。另一方面，建设的工作一旦完成，会想起来就愉悦，而且永远不会因为彻底完成而没有更进一步去做的余地。
You kill your enemy, and when he is dead your occupation is gone, and the satisfaction that you derive from victory quickly fades. The work of construction, on the other hand, when completed, is delightful to contemplate, and moreover is never so fully completed that there is nothing further to do about it.
