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。

Pablo Ruiz Picasso (October 25, 1881 – April 8, 1973) was a Spanish painter and sculptor. His full name was Pablo Diego José Francisco de Paula Juan Nepomuceno María de los Remedios Cipriano de la Santísima Trinidad Clito Ruiz y Picasso.[1] One of the most recognized figures in 20th century art, he is best known as the co-founder, along with Georges Braque, of cubism.
Pablo Picasso was born in Málaga, Spain, the first child of José Ruiz y Blasco and María Picasso y López. He was christened with the names Pablo, Diego, José, Francisco de Paula, Juan Nepomuceno, Maria de los Remedios, and Cipriano de la Santísima Trinidad.[2]
He was Jose Ruíz, a painter whose specialty was the naturalistic depiction of birds and who for most of his life was also a professor of art at the School of Crafts and a curator of a local museum. The young Picasso showed a passion and a skill for drawing from an early age; according to his mother,[3] his first word was "piz," a shortening of lápiz, the Spanish word for pencil.[4] It was from his father that Picasso had his first formal academic art training, such as figure drawing and painting in oil. Although Picasso attended art schools throughout his childhood, often those where his father taught, he never finished his college-level course of study at the Academy of Arts (Academia de San Fernando) in Madrid, leaving after less than a year.
