Robert asked, " I'm just in high school, and I was wondering what I could do to possibly prepare myself to become a storyboard artist."
Personally, I never went to school for it, but if I could go back in time, I definitely would have. It would have saved a lot of time and work, and it just sounds so awesome to be surrounded by students excited about art and animation. Art Center in Pasadena and Cal Arts are both great schools. If you are able to get into Gobelins in France, that is, in my opinion, the best school for animation in the world. Another good school is Sheridan in Canada. Other than schools, just study films and break them down shot by shot into storyboards. that's a really good way to learn. After you learn, studios have training programs where you can get in and learn on the job. TV also has something called a storyboard revisionist. You can basically just show up to any studio with a portfolio of storyboard samples and they will usually call you back and give you a test. Doing the test for the job is actually a great way to learn. I did several test for studios before I finally got a job. every test, I would take to someone in the industry and ask them to look at it and I would try to make less mistakes the next time. that is sort of how I learned to storyboard. Try it, make a storyboard portfolio and drop it off at Nickelodeon.
