My English teacher keeps telling me: " You wont learn anything if you cant make mistake! Making mistake shows you things that you should correct them. That's why you should MAKE MISTAKE! ". My friend! Making mistakes is a natural part of learning a foreign language! And as Niecey says, " The only person you have to impress is yourself! " So when you make a mistake while speaking English, just tell to yourself " WHO CARES?!" and even repeat that mistake if it's funny.

Yes, as Niecey suggests, you could try to describe in your mind or aloud ( a risk of seem a little bit insane ) the things you do during the day, or whatever you are thinking. Just replace russian with english at least 2 hours a day and you will be more confident of speaking with someone else and even if you don't feel completely sure... speak anyways!!!!! I assure you, it's not gonna be a disaster. Relax, mistakes are your friends if you are learning... ^^

Also, it might sound a little crazy...but having conversations with yourself is also a great way to learn a language. The only person you have to impress is yourself! ;D Good luck!

Start off speaking English with someone who is studying another language, that way they understand what it is like to speak another language. Make sure they are patient and encouraging. After you have built up your speaking to a certain point you can start talking more to other people. If talking to a native speaker is too difficult at first, try practicing with another friend of yours that is also studying English. There is less pressure off to speak perfectly if you speak with a non-native speaker at first.
