Certificate Craze (CET6)

In recent years, there are a large number of people who are addicted to getting a variety of certificates*. This situation is out of control. Denser and denser classes have been built and they never afraid of nobody coming**. 
The people who want to get different kinds of certificates have their own reasons. Some of them want to have a good job, while others just think of developing themselves. There are still some people only studying to have fun. They prefer learning new skills to staying at home.
In my opinion, people should choose the useful classes to learn. Learning a new subject would take a lot of time. Once you have decided to learn a new skill, you should have the determination to learn it very well.

*Are you talking about a degree or a certificate? The difference is that a degree is higher than a certificate and takes longer to obtain and required more knowledge.

**I understand the 1st part, however, I'm confused by the end.

Good job though, even with a few mistakes I was able to understand the majority of it.
