数学中最重要的技能是提出正确问题的能力。

I'm going to use all my tools, my God-given ability, and make the best life I can with it.

I dream that my son will grow up to be a good person, a free person. I dream that someday you will return to revisit the land of our childhood. I dream that flowers will bloom in the streets again...and kites will fly in the skies!

如果你不感到不适，你就没有成长。
