Techniques do not matter, rynkrt3; all that matters is your mindset.

LD's are initiated not by clever techniques but by the state of your expectations/intentions, your self-awareness, and your memory. With these fundamentals in place, technique is just a matter of convenience.

Conversely, you will have great difficulty ever having a LD if you only do techniques but don't have time for or interest in mental prep (i.e., doing things like RC's dream journaling, noticing the odd, working on memory and self-awareness, noting dream signs, etc).

So I would suggest that you focus on the fundamentals of lucid dreaming, get yourself consciously to a point where you can't help but have a LD. After that, the technique will become secondary.

Oh, and for what it's worth, my waking-life visualization skills are horrific as well, as are my concentration skills, but I've managed to work around those handicaps -- it may take a little more time and effort than the tutorials might imply to get to the LD's, but you can get there without all the "required" skills... as long as the fundamentals are in place!
