The only limit to our realization of tomorrow is our doubts of today.

"Life is either a daring adventure or nothing at all."

The real challenge is not in solving the equations, but in understanding what the solutions mean.

The only limits you have are the ones you set for yourself.

创新不仅仅是创造新事物；它关乎改变人们的生活。

生活中最大的荣耀不在于从不跌倒，而在于每次跌倒后都能站起来。

有时候你无法独自完成。
