过去总是紧张的，未来是完美的。

The beauty of physics lies in its ability to explain the complex with simple laws.

The financial markets generally are unpredictable. So that one has to have different scenarios... The idea that you can actually predict what's going to happen contradicts my way of looking at the market.

The truth is you don't know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed.

Every tree we plant today is a legacy for tomorrow.
