I think this Worskhop was successful for a few pretty obvious reasons. There is of course returning to your roots and relearning them now that you have the perspective you have now (the advanced dreamers I mean), and perhaps trying other basics that didn't work before.
Keeping up a workbook is a structured record system, and having it presented here in the forum, alongside so many of your dreamer friends, keeps you focused. So many people will be intent one night and not the next... this keeps you consistently thinking of lucid dreaming, and because the results will be tallied at the end of the month, you won't want to quit in the middle.
Pretty good all around, I'd say.
