Creating my own worlds

I've always been good at creating my own worlds inside my head. Those worlds, though, seem to loose something in translation each attempt to put them on paper. I have characters, lives, terrain...everything but a name for this ever-changing world.
To this vain, and because I really must get into the swing of writing again, I have signed up for a couple writing classes via the internet. The first one is a novel writing class, offered by fmwriters.com. I know that I've gotten in, and I'm excited about being able to start. The other two are both offered by Barnes & Noble online university. There's material to buy for that, and when I get paid again, I'll probably do just that. Those classes start on the 9th, and I'm looking forward to it. One is for mystery writing, the other for science fiction writing. Its time that I start the create juices flowing again - and time that I learn to be consistant with it. Writing is not instant gratification, and I must remember this.
