Well, maybe your attention is divided at the source. Perhaps you should not try to perfect one of a few techniques, but to simply lucid dream.
All that requires is the focus to do one thing in a dream. When I started in the Late 1950's there were no publications, techniques, or anything. And I never gave it much thought until in my mid 30's. I just Played and learned in the state.

Since your mind is designed to effect human will, just focus on doing one thing of your choice in a dream--keep it simple.
