你们即将毕业，未来的工作即将展开。并非所有工作都能让你乐在其中，付出的结果并非总是能尽如人意，你们或许会日复一日地饱受煎熬。

你越是积极且实际地投入，就越会感到成功。

Our descendants will achieve things that will amaze us， yet a portion of what they will create could have been made with today’s materials and tools if we had had the imagination. Think bigger.

The harder you work, the luckier you get.
