Are there anything wrong?

Hello, I'm studying TOEFL. It's too hard.
I made scripts but I don't know where are incorrect.
Would you make some correction?

1. Subject: job you want to have

For me, the job I want to have is an interpreter for two reasons.

First, I can travel all over the world. Because interpreters go abroad to work, I can both do my work and experience a lot of different cultures of many nations.

Second, I can meet people from different background and culture. Because interpreters interpret about various fields, they can meet various people whenever they work. I think I can learn many things from the people.

For these reasons, I want to be an interpreter.

2. Subject: job you admire but don't want to have

The job I admire but don’t want to have is a teacher for two reasons.

First, although teachers can feel worth teaching their students, some students are hard to control. I think I don’t have the ability to regulate and control those students.

Second, even though a teacher is the job that guarantees a stable income, it’s very hard to be a teacher in my nation. To be a teacher, I have to pass an exam but the exam is very difficult and highly competitive.

That's why I admire the job teacher but don’t want to have it.

Thanks. I'm always given many helps from this site!
