Books are the nourishment of the whole world. Life without books is like life without sunshine. Wisdom without books is like a bird without wings-Shakespeare.

Books are the ladder of human progress.

If a person doesn't work hard when he is young, he will regret when he is old ―― laziness when he is young will make him regret when he is old; Reckless youth makes regretful old age; Idle youth, poor old age
