Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

"I never doubted myself."

如果你希望成功，当以恒心为良友、以经验为参谋、以谨慎为兄弟、以希望为哨兵。

过去总是紧张的，未来是完美的。

出自《论语·公冶长》。做事情，一定要通过反复的思考，再去行动。
