Distilled to its core, LD'ing is nothing more than drawing on self-awareness ( which is simply being aware that you are
here, that you have an effect on everything around you, and everything around you has an effect on you) and memory (which is turned off during a dream) to establish a foothold for your waking awareness in a dream. Throw in properly set intentions before sleep, which MUST include a real personal interest in actually LD'ing (trying it out 'cause a friend said it was cool is usually not enough), and any technique you choose -- or even make up on your own -- will likely get you eventually to a state of lucidity.
That's the bare bones of it. I did go on at length about these "fundamentals" a while back in my
Lucid Dreaming Fundamentals thread, which I suggest you check out -- I think if you do you'll see more sense in the stuff I just wrote...
