The distance from head to mouth!

Have you ever heard 'the distance from head to heart'?
It has been said, 'it takes usually long time that knowing will become doing'.

I have been feeling nowdays, starting to study grammar, that I had known about English grammar a little from my student's time, so I can not feel 'new'.
Nevertheless, it is matter that I can not speak English well with speedly, naturaly, fluently....
Why can I not speak, hear English?
I think the answer that it is so far from knowing English to speaking English- from head to mouth.

Judy said to us on last Friday, "It is not important that you know well about grammar, but it is important that you hear, speak well English.", and then she said, "Practice, practice, practice, everytime, everywhere, everyhearing, everyseeing, everythinking, everyfeeling. Never Stop Practicing!"
I am here, our room, now I think, "How can we practice English everytime?"

God helps us that we can practice English well.
Give us Your wisdoms, strength, and heart!
Our God has been making us to live by His everything-love, mercy, righteousness, endurance, etc.
God will do it!
Thank you, I love you, my Lord, forever!
I will follow, rely upon You, forever!
