Is driving instructor training really for me

I"ve been trying to make the final decision, but I still have too many doubts. Should I really join driving instructor training? I"m not the kind of person who would do anything just like that, without thinking it over. The course costs a lot and I"m not going to waste my money. Let"s start with the pros. I think I might work with people who are learning to do something, particularly because I have some experience as a teacher. I gave it up years ago, but I used to teach at a secondary school so I think I have enough patience and teching skills. I am also a good driver and I enjoy it. I know a lot about cars and I often fix my own all by myself whenever it breaks down. Well, perhaps except for some major problems. I have enough money to start the course and I don"t mind working in the evenings and at the weekends. What are the cons, then? Well, sometimes I think I shouldn"t join the driving instructor training anyway. Although I like driving very much, I must admit that I break traffic rules quite often. It"s just too tempting to drive a little bit faster than I should sometimes, and I can"t stand waiting too long for the green light to appear. If there is nobody else at the crossroads, what"s the difference? Well, I think I will have to make up my mind and decide if I am going to take part in the driving instructor training or not.
