Can I ask something??

I have been learning English for a long time.

But, recently, I feel that I STILL don't speak or listen well.

And Also, I'd found many ways to improve my English skill.(for example, studying Grammar In Use)

In Korean, it is common to start a sentence with 그리고 or 근데.  These words can translate to 'and' and 'but.'  However, you cannot start a sentence in English with 'and' or 'but.'  Try using 'also' or 'however' instead.

But, I am a little bit doubtful.

I want to know how you've studied English (or do you know one of the best ways to listen to and speak English?)

While I am typing this now, I lay the GIU next to the laptop on the desk.
