That's an important idea. I am often involved in language environments and there are linguists among my friends. One of them remembers his days at university when he was studying languages and linguistics, foreigners were among his professors there. So the idea is:
When speaking a foreign lanuage one has to KILL Russian structures in them. So you see Igor. That's basic advice, and that's what professionals say. Just KILL the Russian structures, it's an important step. You may even choose to speak simple English, but just forget about Russian when you do it. It's hard to do without proper training and inner work I suppose, hard to do it on your own. The problem is that Russian structures are so deep in us, they are extremely difficult to destroy. I hope that might help you in your work, good Sir Igor!
