Let Books Be Our Good Friends

    Books are our friends because they are bridges to knowledge. Knowledge is valuable because it enriches our life and brings us happiness.

    Almost all great men in the history of mankind loved books. We have every reason to believe it is the knowledge in books that led them to success. There is no genius without books. Because books give them knowledge and knowledge gives them power. A man is half blind if he is unable to read.

    Books make us able to learn about the past and look forward to the future. They are the most valuable things in the world. Let books be our good friends all the time.
