All time is no time when it is past.光阴一去不复返。
A lazy youth, a lousy age.少壮不努力，老大徒伤悲。
Better a witty fool than a foolish wit.-Shakespeare 宁为聪明的愚夫，不作愚蠢的才子。－莎士比亚
A light heart lives long . 豁达者长寿。
Do not , for one repulse , give up the purpose that you resolved to effect .
不要只因一次失败，就放弃你原来决心想达到的目的。
In delay there lies no plenty , Then come kiss me , sweet and twenty , Youth’s a stuff that will not endure .
迁延蹉跎，来日无多，二十丽姝，请来吻我，衰草枯杨，青春易过。
The time of life is short ; to spend that shortness basely, it would be too long .
人生苦短，若虚度年华，则短暂的人生就太长了。
Don’t gild the lily.
不要给百合花镀金/画蛇添足The empty vessels make the greatest sound .
满瓶不响，半瓶咣当。The course of true love never did run smooth.
真诚的爱情之路永不会是平坦的。
