During my teacher training course I visited the lessons of a teacher who impressed me very much. Before (going to see her teach) I was not sure I wanted to be a teacher, I took the course because we could choose it at university.
But when I saw her teaching, speaking about the teaching, her energy, stamina and motivation, I decided I wanted to do the same job.

Two months later I was offered the job in the same school and so I became a teacher.
