     Diligence is the key to success, which means persisting in one's work.The true meaning of diligence is

to use time carefully for the purpose of improvement, or to work persistently without wasting time.

     Laziness makes us useless.If we do not study and work hard we shall not be able to earn a living in

our community.There will be nothing we can do just because we have failed to learn anything by letting

the time pass unused.The life of a lazy man is of no use to himself and to others.The man who is too lazy

to work is the man who's generally most ready to beg or to steal.Everyone when he is young should learn

some useful work.

     There is no better help to diligence than the habit of early rising, which just like all other good habits

ismost easily formed in youth.An English proverb says, “Lost time is never found again.” This means

that everybody must be diligent, and make good use of his time.Time is precious and is one of those many

things that cannot be purchased with money.One must study hard when he is young so that he may make

great progress, succeed in life and become useful to his country.

Lazy hands make a man poor, while diligent hands bring wealth.Therefore, we can say that diligence is

the mother of success.
