Just think of the reasons you want to LD, what you want to do and why. What its going to mean.... You want to LD?

GET THE BLOODY DJ FILLED IN!!

In all seriousness though, recording your dreams is going to help you remember your lucids and build dream recall. Can you imagine how much you'll kick yourself if your having lucid dreams but not actually remembering them? That would suck major ass!

I know how you feel, i often get unmotivated "oh that one was pretty vivid, ill jot it down later" - face it man, later NEVER comes and it doesn't get done. Try to make it your routine that you wake up, grab you DJ and make some scribbles. Even if its just a few short words that will help you remember in the morning.
