It doesn't have to be anything you can finish, just write down whatever ideas you can. I don't think most people are able to start many of their ideas and projects. I know I have several projects I've planned on starting, bought databases, templates, etc.. and haven't gotten around to it. I don't think any serious project you'll get done in one day, they all require work and learning as you go. Just write down whatever you can, and take notes, since some day you might be out of ideas and you'll have notes to go back and refer to.
If you're really really new, and don't know how you're planning on starting. Just keep reading first until you can get a grasp as to what's going on. Also mentioned was to check out
Webmaster Forum - Internet Marketing & Search Engine Forums There are a ton of noobs there in the same place as you. You haven't mentioned what you want to start with, ppc campaigns, blogs, etc.. Once you get started with that, then you can make more specific posts about, what you want to do and what you're unsure of. That's what this board is for, is to explain what x,y,z is, but first you have to have a project to work on.
Your goals to start with should be, which method do I want to use to make money with, as suggested in another response above. Then start searching for threads on those topics, most likely any noob questions have been answered. When you actually start on the project and get stuck then start asking questions.
If you keep reading this thread and responding to it, you're not being productive (just as I'm not). Nobody can say much else except to just start doing something. Start thinking of niches you can get into, that's how I first started and started making money was constantly thinking of niches where there isn't much competition (since I'm new), but is still a profitable niche.
