You want to feel like yourself when speaking English.
You're comfortable with your English skills - except for how you sound when speaking.
You know that you need to express yourself as clearly as your American colleagues and friends do.
You'd like to sound as articulate, intelligent, and natural as you do in your native language. (And not have to worry about repeating yourself because of your accent.)
You would love to participate confidently in small talk, ask questions and give answers that create conversations, and sound more professional in discussions.
