How did the teaching practise change my idea of how I see myself as a 'teacher'?

The school I went to for my first teaching practise was the school where I was last year. Everything was the same even the students, so I felt very comfortable there. The first time I stood in front of a class the reality strike me. I thought to myself this is the thing I am going to do every day of my life. When the student called me sir I was blushing just to see the respect they showed me even thou I am there friend. I also learned that teaching is not a half workday job like everybody else told me. Your job as teacher does not stop, not even on weekend or holidays. I also learned that teaching is not just standing in front of a class, but a lot of admin too. I learned a lot after my first teaching practise and it is still my dream to become a teacher one day.
