I'm working with English natives, and in our meetings I have the same problem - I don't fully understand what they say, and moreover, when I'm trying to say something, I'm trying to form my thoughts in my mother tongue and then translate them to English - and that's wrong. But one time, being in the meeting, my brain switched the language, and I started to listen and think in English, without translating to Russian. Of course, I didn't became to understand more, but conversation was more productive and more natural. Al least I hope so. Unfortunately, next meeting was going as usual, I didn't find that English vibe.
