Motivation problems for 6 months

[Yuusha]

I have been practicing lucid dreaming on occasions for about 3 years, and I have had about 30 lucid dreams, some quite amazingly vivid. However, now I haven't been able to feel very motivated at all for almost 6 months; my last serious practice time was throughout February this years, and that month I practiced MILD and overall awareness every day and evening, and I got 5 or 6 lucid dreams that month. But ever since then, I haven't been serious about lucid dreaming at all, but I wish I could be. I have been quite occupied with school stuff lately, so I guess this is a distraction, because I tend to have an easier time with lucid dreaming if I have a holiday and am free from any immediate concerns (right now I am practicing for a math test that I will have in about two weeks, so I am fairly "occupied" right now as well). I can sometimes feel small bursts of excitement when I watch lucid dreaming videos by serious lucid dreamers like Stephen LaBerge, Robert Waggoner and Tim Post, but that excitement quickly wears off. I sometimes also fantastize about things that I really would like to experience in lucid dreams, but my reaction is more like "yeah, that would be awesome - but some other time". I have no idea why I think this way. What should I do to regain that more constant feeling of excitement and motivation again?
