     Getting paid to talk about the World Cup is a great job. I' m not a football commentator (评论员),

though--just an English teacher in Japan.

     I came to Japan two years ago, and didn' t think I would stay, but Japan has that effect on you.

People often end up living here longer than they planned. I think it' s best to teach, in a bigger city

where there are other foreigners to mix with, rather than a small town where English teachers often

complain of feeling like a goldfish in a bowl. Many people choose to live in Tokyo, of course, which

is good for tile nightlife factor. But I' d say that for general quality of living, cities of neither too large

nor too small, like Sapporo where I live, are better choices.

      I teach English privately, which means I' m my own boss. If you want to devote yourself to private

teaching, it's well worth doing a TEFL course first, because your lessons will be much better for it. The

problem with private teaching is finding students; it took me a year to build up a full schedule (日程表)

of private lessons, so I started out teaching in schools part-time.

      Most of my foreign friends here work full-time for big English conversation schools. The salary is

fine to live on, but whether you can save money depends on how much going out and traveling you do

here.

     The schools are reluctant to take time off -- even teachers with tickets for the England-Argentina game

had trouble getting the day off.
