A little about me and my work:

Hello everyone!

My name is Ainara, I´ve am 24 years old. I´m working in a dentis because I´m as a dental hygienist. I´m have been working 2 years ago, since I was finished my studies. I will would prefer working to work in anything relevant with something related to sports, because i love do it and to practise it. But this jobs hasn´t got departures (maybe the best way is to say - but this industry doesn't have any openings or opportunities). So i decided to study dental hygienist, at the first moment I thought that i didn´t like this job, but suddenly when i was worked, I have changed my opinion having worked there, and now I love it.

The things because I want this job, it´s for example, that I have to work with a lot of people who have pain in their teeth, and the doctor and me can do that persons feel good.

This sentence is a bit difficult. I think the best way to say it would be - 

There are many reasons that I like this job. One example/reason/benefit/positive is that I work with a lot of people who have problems with their teeth, and the doctor and I can help them feel better.
