My goal is to become fluent enough to speak intermediate Mandarin by 2010. That is when I'm taking my wife and three boys to Taiwan to pick up their brother who is currently over there doing volunteer work. In order to reach that goal, I have purchased a Mandarin program and I listen to it for half an hour every day. I have a co-worker who speaks Mandarin and is willing to practice with me. There's also a Chinese grocery store in my town and I speak to the owner in Mandarin whenever I drop by which is about once a week.
