Hello Takashi, I am more than happy to help you out.
First, just general formatting when writing, try to place space marks after your punctuation (ex. periods).

Compare:

"I'm Takashi.I work as a bus driver..."

"I'm Takashi. I work as a bus driver..."

I'm Takashi. I work as a bus driver driving from the airport to Tokyo. I want to give to guidance in English. But my English is very poor. I want to be good at English. I am interested in the culture of the other countries. I'd like many friends.
Thank you
