Take time to deliberate, but when the time for action has arrived, stop thinking and go.
事前考虑清楚，可是一旦到了该行动的时候，就要毫不犹豫，放手一搏。
一切人类知识都源于经验。
Old paint on canvas, as it ages, sometimes becomes transparent. When that happens it is possible, in some pictures, to see the original lines: a tree will show through a woman's dress, a child makes way for a dog, a large boat is no longer on an open sea. That is called pentimento because the painter 'repented,' changed his mind. Perhaps it would be as well to say that the old conception, replaced by a later choice, is a way of seeing and then seeing again.
真理是人类精神的自由创造，如果我们自己不产生它，它就永远不会存在。
The most important thing is to have a disciplined approach.
