an english proverb says that time is money. i consider it (this) wrong. why? because we all know that we can earn money be work but can not in any way get back time (in anyway). for this reason, we may (can) say that time is more valuable than money.
many people do not know the value of time. it (this) is indeed a great pity. we must bear (keep) in mind that wasting time is equal to wasting your life.
