My Life Has A Direction...And Is Gaining Velocity

I have finally, after 18 years of life, have decided what my sole purpose is. I know, I know. I said the same thing when I was six when I wanted to become a mermaid, or all of middle school when I thought I was going to be an actress. But this time it might actually work out. My goal in life is to be Jon Stewart. If you don't know who he is be thankful that I cannot slap you through this computer. Go ahead...go Google him..I'll wait....Ready? Now, obviously I cannot actually BECOME Jon Stewart, but once he becomes to old to do the amazing job we have all come to expect (which will be a horrific day indeed) I will gladly take his place. You may still be thinking that this will never happen. Possibly. But to ensure that this could be a possibility one day, I have decided my life long goal will be to become a writer for The Daily Show. Sounds simple and realistic enough, right? Wrong. First I have to become a member of the Writers Guild Association, meaning- I have to be employed as a writer over the span of three years AND THEN I have to pay them $2,500 for a membership. After that (or before or during) I have to get an internship with The Daily Show, assuming any are available. I've come to find that they very rarely are. I also need to make some massive connections with some head honchos at Comedy Central, and if you've known me for more than four minutes, you know people are not my strong suit. During my internship I can offer jokes for the show and IF they are chosen consistently AND the public responds to them favorably, I MAY get hired. Should I be concerned that this is the most plausible career path I've ever had?
