所謂智慧，就是擁有的問題比答案多。

The key to successful investing is to have a clear understanding of the market, the risks involved, a disciplined approach, a long-term perspective, a strong understanding of the fundamentals, a clear understanding of the risks and rewards, and a strong understanding of the market psychology.

好的科學既需要創造力，也需要紀律性。

Short-term gains should never come at the expense of long-term sustainability.
