Youth comes only once in a lifetime, therefore, it is important that we should not waste those years in idleness and bad living.

This is also the time when our memories are best.We are able to learn more during this time than when we become older. During our younger years, we have the enthusiasm to set high goals for ourselves. We also try to overcome obstacles which are placed in our way.

If we realize how precious youth is, we will be fulfilled when we are young as well as when we are older. If we waste our youth, we will spend the rest of our lives wishing we could be young again.

译文：青春只有一辈子，因此，我们不应该浪费那些年在懒惰和不好的生活中。

这也是我们记忆中最美好的时光，在这段时间里，我们可以学到更多的时间，而不是变得更老。在年轻的岁月里，我们有热情为自己设定高目标。我们也尝试着去克服阻碍我们前进的障碍。

如果我们意识到青春是多么珍贵，当我们年轻的时候，我们会满足，当我们长大。如果我们浪费我们的青春，我们将度过我们的一生，希望我们能再年轻一次。
