What’s teaching English for me? (It's an essay for a job interview. Would you mind checking it please?)

A lot. I belong among those people who believe that work should bring happiness since we spend half of our lives there.
Why teaching English can make me happy?
Firstly, it’s rewarding to see the progress your students make.
Secondly, it’s satisfying to see that the approaches you’ve invented to meet the demands of every person, you deal with, work.
Thirdly, this job keeps you curious. Being a teacher you always have to find answers to your questions and upgrade your knowledge. Psychologists say that the deepest happiness is the one you feel when your curiosity is satisfied.
Finally, it helps you to keep your mind sharp and soul open because you work with people who always need your understanding and appreciate your honesty.
To sum it up, I love teaching English for giving me a chance to evolve as a human being not only in my personal life but at work as well.

This year I had wonderful experience with a girl from a common state school who wasn’t good in English. She lacked confidence and panicked facing every tiny handicap on her way. My task was to comfort her, create the necessary atmosphere and help her to develop her linguistic intuition. As a result she succeded in the State Exam. She got 74 points out of 100. That was incredible taking into account the fact that at the beginning of the year when we met she could hardly tell what Present Simple was. Of course, I can’t take credit for this result since a student does 70 per cent of the whole work, but I was happy to find the encouraging words which could help her move on when she was about to give up.
