Personally, I feel like I want to master a main technique or two, rather than keep changing. I think part of this is some minor health issues which have been compromising sleep. It could also be from forgetting to set my intention to have lucid dreams for several minutes before going to sleep and when I next wake up. Somewhere I've heard someone post that they find SSILD much more effective when they spend 3-5 minutes repeating their intention to become lucid.
