Why I want to be a driving instructor

I"m a secondary school student. Yesterday we discussed our future careers at school and our teacher asked us to write a short description of our future career at home. I know that most of my classmates want to be somebody unique like a singer, a famous athlete or even a politician. But I"m thinking of something more realistic like becoming a driving instructor. I"ve even started researching on the subject. You have to enrol for a special course which may last from 12 weeks to 3 months, depending on the driving school and your progress. You must attend some theory classes, then practical classes, and pass special examinations to become an ADI (Approved Driving Instructor). I will have to study a lot and also start saving money. And the most important thing is, I must be a driving licence holder. I want to enrol on a basic driving course as soon as I"m old enough. I want to become a driving instructor because my dream is to be independent. Boring office work is not for me. I don"t want to live in a kind of company hierarchy; I was not really cut out to do this. And I love to explain various things to other people. My classmates often ask me to help them at Maths or Science. I have also taught my younger sister to ride a bike. I think I have all necessary characteristics to become and instructor, I only need more time, money and motivation to make my dream come true.
