出自汉·桓宽《盐铁论·忧边》。因，根据。知，通“智”。明智的人根据时机而改变行动方案，智慧的人随着事情的发展而制定不同的应对策略。这句话言随机应变、因事制宜才是明智者。明智的人，因时间的推移而进行改革；聪慧的人，依世情而制定治国方法。
There is no man, however wise, who has not at some period of his youth said things, or lived in a way the consciousness of which is so unpleasant to him in later life that he would gladly, if he could, expunge it from his memory.
迈向可持续实践的每一个小步骤都很重要；完美不是目标，进步才是。
合理的战略始于树立正确的目标。
Writing is a way of life, a way of being in the world.
