Staying or Working in foreign countries .

I have wanted to visit a foreign country ( especially the UK ) because I love to drive a special car built in there . I sometimes think it is not easy to live there if I could visit the UK , because I have seen some person who quickly suddenly（のほうがいいとおもいます) left my country before . They were an ALT( Assistant Language Teacher ) here in Japan . I think all of them had the same hope as I had . Why were did they leave within about a half year ? It depends on each reason Everyone has their own reasons of course (自然な表現), but if there are is a common reason , what is it ? pPlease correct my sentences . And if you have similar ideas or experiences , give me your ideas as possible much as you can . Thank you .

Masato さん、

興味深いの質問です！

人々が外国に期待を持っている、でも現実は異なっている.

多くの予期しないものがあります。

刺激は大切です思います。

このトピックの詳細を書きたいが、私は今仕事をしなければならない。

Masatoさんが言語を学ぶ意欲を持っているので、何も問題はありません。イギリスに来る必要があります。頑張ってください。ところで どんな英国車が好きですか？
