A、He didn’t like physics any more. B、His eyesight was too poor. C、Physics was too hard for him. D、He had to work to support hims

When I was at school, my ambition was to be a pilot in the air force. But my eyesight wasn’t good enough. So I had to give up that idea. I went to university and studied physics. 1 wanted to stay on there and do research. But my father died at about that time. So I thought I’d better get a job and earn my living.  I started working in an engineering firm. I expected to stay in that job for a long time. But then, they appointed a new managing director. I didn’t get on with him, so I resigned and applied for a job with another engineering company. I would certainly have accepted the job ff they had offered it to me. But on my way to the interview, I met a friend who was working for a travel agency. He offered me a job in Spain. And I had always like Spain, so I took it. I worked in the travel agency for two years and then they wanted to send me to South America. But I had just got married, so I decided to stay here. Then we had a baby and I wasn’t earning enough to support the family. So I started giving English lessons at a school in the evenings. I like the English teaching more than working for the travel agency, and then the owner of the school offered me a full time job as a teacher. So I resigned from the agency. Two years later,  the owner of the school wanted to retire, so he asked me to take over as the director. And here I am.
