Life can only be understood backwards；but it must be lived forwards.

The only real failure in life is not to be true to the best one knows.

"The wings of Icarus might not be far away. Rather than fearing the possibility of failure, I’d rather fly and fall."

只因为有庸俗的念头，一生的做事皆错；只因为俗眼观人，而一生没有认清朋友与敌人。
