Just start speaking, don't be afraid. Maybe at first time you'll feel shame or something like that, but try to focus on the person you speak to and the topic you discuss instead of focusing on shame or word correctness. Try reading this guy's blog: http://www.fluentin3months.com/ or if you can understand English well enough, I'd even recommend watching his TED talk: http://www.youtube.com/watch?v=0x2_kWRB8-A He is very inspiring! A meditation usually is a good preparation before some stressful conversation ;) By the way, in which country are you hesitating to speak English?
