London University is one of the (highly) appreciated universities in the world, therefore, I wanted to be accepted there. But I was lucky and I was accepted there. I (had to) make two trips to London before I started one for the interview and another to find accommodation. The university provided students with information about flats. By the time the semester began, I (had already found) a place to live and a roommate. While I was studying, I didn’t think about work and how I (am earning) my living after university. When the time came, I realized that languages had always interested me so I applied for several jobs to teach English abroad. Obviously, I didn’t have any experience but I thought I had a small chance of (being accepted). In the end, a letter came and I felt nervous as I opened it. But the news (was) good! The letter offered me a job in a Swedish school. I knew the winter weather in Sweden was cold so I bought some warm clothes. Then I had a farewell party and everyone wished me good luck in my new life as a teacher. Since then I (have had) a lot of jobs in different countries and I am happy to say that I have enjoyed all of them. But I have wondered many times what (would have happened) if that first letter had turned me down.
