Hello, and welcome! Yeah, I can feel like that sometimes; I want to do it some days, and others I'm not bothered to. What I do to keep my motivation up is pretty much stay active on this forum, read about lucid dreaming and think of it everyday. Maybe that'll help ya.

We gotta stay consistent with the techniques we use, or at least use one for several weeks before giving up on them. Just stay motivated and you'll get there!
