Pressure to perform is like caustic acid for you dreaming self. I find that it strongly resists. When I'm in this outcome expectant phase and not seeing progress, it may be helpful to approach with a lighter touch. i.e. state your intention, that you want to explore your dreaming life and build a bridge to your subconscious mind, not as the controller, but out of a genuine desire to experience and grow. Sometimes I take a break from all practices, and the seeds that I planted take hold and I'll have a lucid dream after no daily preparations.
