An English proverb says that time is money.
I consider it (this) wrong.
Why?
Because we all know that we can earn money by work but can not in any way get back time. 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.

　　爱 惜 时 光

　　英国有句谚语说，时间就是金钱。
　　我认为这是不对的。
　　为什么？
　　因为我们大家都知道我们能够用工作赚钱，但无论如何却无法把过去的时间争取回来。
　　基于此种理由，我们可以说时间比钱更宝贵。
　　许多人不知爱惜时光。
　　这确实是可惜的。
　　我们必须记住浪费时间等于浪费生命。
