Old Habits Unfortunately never die

So I've had this problem for almost my whole life now. Words just tend to leave my mouth faster than then are thought of. I was when I was either nervous or not nervous, so basically all the time. I went to speech tutors in elementary school and middle school. I also went to an independent speech specialist. My parents tried all they could to help me, I guess be understandable. I was ok my senior year of high school, and I knew I had to somehow combat my speech problem in college. Socializing and being by myself, I had to know how to people and in front of people. I still slip up every now and then, because even though I picture myself saying the word normally and correctly, I still somehow slur or say it way to fast. It becomes even a greater problem when presenting. Everyone is staring at me and listening to what I'm saying, and I get so nervous. This was the case today for a job interview I had. First of all, I was expecting a old white dude, and got this hot asian chick. So right off the bat, I was a lil' intimidated. If you're an employer reading this, take this advice: DO NOT SEND A YOUG LADY WHO IS ATTRACTIVE FOR THE RECRUITING, SEND MIDDLE-AGED TO OLD PEOPLE. I caught myself just looking at her, and not really focusing in on what she was saying. The VERY first question she asked, I said the answered the whole thing in like 1 minute. After I was done, she asked me, "Do you speak another language?" I spoke so fast, she thought I spoke another language. At that point, the very first question, I knew I didn't have the job. But I had to keep a positive attitude, to keep myself going and not feel awkward or embarrassed about it. So I said no and just told her I was nervous. After that, it got a little better, as I told her about myself and everything. I asked her where she's the company in 5-10 years, and she gave me a good answer. What I wasn't expecting was for her to give me the same question. So I answered it, and she started laughing. This interview was like a kick to the nads. I told her about 4 different things, and she laughed, and told me that was a lot of things and very broad. So then I said that I had no idea to be honest, but probably a consultant. If I get a call back, I'll be very surprised. Horrible interview. Now I gotta start applying to more jobs.
