在我看来，自然界是最大的兴奋来源；最大的视觉美来源；最大的智力兴趣来源。它是生命中许多让生活有价值的东西的最大来源。
It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.
The only thing that stands between you and your dream is the will to try and the belief that it is actually possible.
不要害怕冒险——大多数伟大的发明都来自大胆的实验。
