I will consider learning English well and coming to Australia, Canada, or Europe.

Which country is the best place to live?
Is the happiest country in the world really happy?
Why can't Japan's happiness level increase?
I learned that many Japanese young people like to work in countries like Australia, Canada, and New Zealand.
Because the salary level there is really higher than in Japan.
It is said that working in Australia for one month is equivalent to one year's salary in Japan.
