Heh, it's pretty awesome that you could actually remember what you wanted to do in a lucid dream, when actually having one! Sadly, I don't think you will get consistent lucid dreams just by doing nothing - the reason, I believe, that you got two today, is because you were thinking about them a lot - LDing is a an exciting concept, and so just because of that you got two. I also had a (my only) lucid dream pretty much right after I started training to do them, but nothing yet since then - my excitement isn't as intense anymore. Either way, good luck - you're off to a good start!
