Regular speaking is definitely important. I'll add a related advanced tactic. Switch your inner monologue language to English. So whenever you're thinking with the help of language, do it in English. This will go a long way towards making your verbal speaking faster and more natural, because you'll no longer be doing quick translations in your head. To be more precise, at least for me, this thinking language system seems to be heavily influenced by learning. I've been doing most of my thinking in English for the last decade or so, and most of the things I've learned during this time are stored in my head in English. [1] However my earlier life lessons are still in my memories in my original native tounge. This is interesting because I started learning English more than 25 years ago, but even things I consumed in English got translated and stored in memory in my native language. -- [1] Of course there are more factors in play than just thinking in English. I've also been better than ever in English and English media makes up for a larger percentage than ever in my total consumed media. I'm sure all of these and more have played a role, in addition to changing my inner dialogue language, in storing my memories in English now.
