There's no such thing as a free lunch.

天下没有不劳而获的事。

Everything has a price.

每件事都有代价。

If you want to be successful, you must pay the price,which is hard work.

你若想成功，就必须付出代价，这个代价就是努力。

Success does not come to those who are idle¹ and waste time.

懒散又浪费时间的人是不会成功的。

It can, therefore, be said that hard work is the key to success.

因此，我们可以说努力是取得成功的秘诀。

To put it differently, if one desires to succeed in everything, he must pay the price-work.

换言之，吾人事事都想成功就得付出代价——工作。
