How can I speak more English more fluently?

Currently I am studying English but even though I feel what that I know a lot of much about grammar but I can't speak well. If someone knows how I can improve my speaking fluency in English (fast and easy), please let me  You know what kind of exercise I can do.

I am sorry to burst your bubble.  There is no easy and fast way to learn any language.  You just have to practise everyday, ideally with a native speaker.  Of course this not possible in real life unless you live in a country where they speak the language.  Even so, I wanted to learn Spanish but still living in Los Angeles with a large population of Spanish speakers, I still don't have the chance to do so!

Here in italki, the best for you is to write and get corrected.  Be thick skinned to ask questions regardless if they are silly or not.  I always believe that if you write well, you can speak well and vice versa.
