Practise speaking to others every day! This question has been answered on Italki many times already.

I think the more you listen the more you be able to "express". It all about how to say expressions, unless you have heard it before you will never be able to go fast, you have to be slow to build yr own ones and this does not function, of course after listening daily you need to communicate with native speakers the thing that never happened to me, I only type in keyboard !
