The world is so unpredictable. Things happen suddenly, unexpectedly. We want to feel we are in control of our own existence. In some ways we are, in some ways we're not.
幸福并不容易。很难在我们内心找到它，更不可能在别处找到它。
世界不是游乐场，而是思想和利益的战场。
【译文】 孔子在河边说：“时光如流水！日夜不停留。”
The key to sustainable growth is balancing short-term gains with long-term vision.
Persistence is more important than brilliance in scientific research.
