I have a (paper) dream journal, but I'd usually only write in it when my dreams were really vivid or interesting.

Yesterday, I resolved to write mine down no matter what, even if I could only write down a few words. My lucid dreams had been so few and far between, and I just got sick of all the dry spells.

Last night I was so determined to write my dreams down, when I fell asleep and my dream switched scenes, I tried to write my dream down within my dream. My dream switched scenes several more times, and I had several false awakenings in which I tried to recall my dreams... and it happened so many times, I tried a reality check and BAM! Lucid.

Makes me wish I had started seriously journaling sooner. ^^
