I'm not that different than Kind of Blue (just with less talent) in how I started. I just started copying pictures from comic books, book covers, hockey cards, anything that caught my attention. It just became a daily thing (ask my school teachers). Everywhere I went I had a sketch pad and pencil with me. By my mid teens I was hanging out with other people who also drew all the time, and it became almost a competition in a way. We all were inspired by, and tried to top, each other. And seeing other people's work always stirs that competitive edge in me.
I took art classes, but for me I didn't get a lot out of them. I won't say it was a waste of time at all. I did learn something, but by the time I got to art school I knew exactly the type of art I wanted to do (I'm a sucker for hyper detailed line work in pencil or pen and ink). I got a lot out my Art History class. Like Kind of Blue says, it really gives you an appreciation for all types of art, and that's been awesome. Everyone said I'd be bored silly in the class and instead I aced it with 4.0 and loved it.
The mistake you're making is one that we all make at first. We worry too much about comparing our work to those who have already been doing it for awhile. No one picks up a pencil and immediately knows all the things a simple #2 pencil can do. I just had someone send me a PM on Myspace asking about my art, and he wanted to draw awesome right away, and got down on himself for not being able to do so. I told him the only picture you should ever compare your work to is your last one.
One lesson I was shown real early is a simple one. Draw ten empty squares. Color the last one totally black and leave the first one totally white. Now fill in the eight squares in between, slowly going from white to black. You start to see just how many shades one can get from a pencil, and that was a fun feeling. There's really no secret to drawing. It's just practice all the time. Even doodling isn't hurting.
If you're into fantasy art here's a couple very cool sites to check out.
