　　Hello, I am Sonia Comez from Argentina. I have a very exciting job, which I would like to tell you about. I am a mountain climbing instructor in Patagonia. Patagonia is a large area covering Argentina and Chile in South America. It is one of the most beautiful places in the world, and it has mountains covered with snow.

　　Becoming a mountain climbing instructor was a natural choice for me because I have loved the outdoors ever since I was a child. My family and I would often go walking in the mountains. Although I studied business at university, I did not want to work in an office. One day, just after I had graduated I saw an advertisement for mountain climbing instructors at Southern Way Mountain School. I applied for the job, and because of my previous experience, they hired me. I was sent on a training programme for mountain climbing instructors. Then I took a test to show that I knew the proper climbing techniques and that I could guide others. Now, seven years later, I am the assistant director of Southern Way Mountain School.

　　My job requires many skills. First of all, I must be a good teacher, as I have to explain mountain climbing techniques and safety rules. Because tourists come to Patagonia from all over the world, language skills are also important. My first language is Spanish, and I am also fluent in English and French. Finally, mountain climbing can be dangerous, so I am trained for emergency situations, such as how to give aid to and rescue someone if they fall or get hurt. If someone gets hurt, I have to figure out the best way to get them down the mountain without causing them any more pain.

　　Being a mountain climbing instructor is a great job for me. Every day, I get to be outside and enjoy beautiful scenery. I meet people from all over the world, which makes my job even more interesting. As the assistant director, I am using my education in business to make decisions about the school's budget and hiring new instructors.

　　I want you to know that it is possible to combine something you love with a career.
