[EN] thinking in English

Hi everyone, nice to see you.
This is my first post written in English, except the formar test post :-)

It's very hard to write something like dialy in English, I think..
In Japanese language, we can write anything which comes to our mind as soon as we do.
I heard that thinking in English language is good for speaking/writing English well, thinking in Japanese language needs to be translated in our brain, and it often becomes wrong English.

Thinking in English?
My English is too poor to do that...

What can I do for that(think in English well)??
