Pieces of translation?

Nowadays, most of the profits of doing business-sometimes even all the success-depend on making good use of "scraps". These "scraps" may be all kinds of small things. They stayed after the main products were produced. However, they do have their real value. They exist in all industries. For example, in a large bone meal factory, there are countless kinds of "leftovers"-bones and hair (just mentioning a hair does not need translation). Bones can be made into paste, and hair can be used to make ropes. If these little things are ignored, it means that the factory will lose a lot of profits.

We students also have our own "leftovers". Take time as an example. Everyone has the same time. Success depends on the use of time. However, the way we use time is similar. Do your daily work well: attend classes regularly, or spend a few hours reviewing your lessons, and then the day will pass. But what about these "fragments" in the rest of the time? Many scientific geniuses and artists occupy a place in this world, mainly because they make full use of their remaining time. For example, when Thomas Edison typed for a living, he never allowed himself to waste any spare time. He thinks, plans and takes the time to try. Later, he succeeded in inventing many unprecedented new things. By making full use of his spare time, Edison brought valuable wealth to the modern world. Think about a short fifteen minutes before breakfast, half an hour after lunch, even going to the toilet and taking a break. Pay attention to using the spare time that appears from time to time in the day to read and think. Make full use of every minute, and you will find real benefits, just as business tycoons have found.
