当你怀疑自己能否飞翔的那一刻，你就永远失去了飞翔的能力。
"The moment you doubt whether you can fly, you cease for ever to be able to do it."
"The only way to create real prosperity is to provide people with the freedom to innovate and create value."
The secret of change is to focus all of your energy not on fighting the old, but on building the new.
"The past is always tense, the future perfect."

我教育孩子们要独立——就像我自己一样。
