How to progress spoken English skill more effetively

Hello friends at LingQ.

I have been learned some contents of Steve’s book “The Linguist”, and it’s beneficial for my learning English and Japanese, but i still feel some times it difficult to express myself. The oral skill of new language, it seems so different from reading or writing, even listening skill. I mean it seems more difficult to mater it or get more fluent.

Thanks for any advice for that in advance.
