举轻若重，且举重若轻。前者可以避免疏忽大意，后者可避免丧失信心。自以为一件事已经完成，它便永远无法完成。另一方面，勤奋且有耐心，可以攻克看似不可能的事情。想要成就大事，不必过分思虑，以免知难而退。
attempt easy tasks as if they were difficult, and difficult as if they were easy: in one case that confidence may not fall asleep, in the other that it may not be dismayed. for a thing to remain undone nothing more is needed than to think it done. on the other hand, patient industry overcomes impossibilities. great undertakings are not to be brooded over, lest their difficulty when seen causes despair.
