well, my problem is that i have so many things i want to try, but i can't gain lucidity often enough to try them all out

if you feel there is something missing, i think it is because deep down inside you there is a creativity or curiousity lying dormant, waiting to be let out. It isn't anything outside of yourself that is missing in your lucid dreams (how could it be? your LD's are created SOLEY from your mind). It is some aspect of your consciousness that you are ready to manifest.
sort of like magma inside the recesses of a volcano, building up more and more pressure, getting closer and closer to release. perhaps that growing pressure is what you are feeling.

you must find that out yourself...good luck
