I am going to travel abroad to visit schools (for my business), so I would like to be able to introduce myself properly.
If you could help me, it will be so lovely of you :) 

Hello everyone,

It's very lovely to meet you all and thank you so much for having me today in your school. 

My name is Mayumi.C and I was born and grown up in Japan.

I have been teaching for over 15 years mainly in Japan but I had a opportunity to teach Japanese language in Australia.

I just love my job very much and I think I am very lucky to find a job I can love so much.

When I was your age, I had no idea what my future was going to be.

And I didn't have any good older friends to give me any good advise, so....

(this is going to be very long, so I should stop here :)
