i've been really confused about RC's, when I joined the forum I was all about making them habitual which never really trigger any lucids but make me think damn alot about ld's which I belive increased my recall, I would wake up and instantly think about LD's and what I should do to get closer to having one. In short I think it help my motivation.
I also think this became incorporated into my dreams as my first lucid was trigger by me having a conversation about LD's and demonstrating that light switches dosen't work in dreams.
Now I don't do them unless somthing wierd happens because I heard that's the way to go, but I just don't know whats the best method.
