Routine activity conditions the brain to follow old, familiar neural circuits. Over time, new input has a harder and harder time registering, because the course of least resistance is to follow the same ingrained patterns.
Notice that routine isn't a problem in and of itself -- keeping regular hours, going to bed at the same time every night, and maintaining a regular health diet are all good for the body. The real problem is located in the mind, which is the seat of consciousness. Every day your mind controls a feedback loop where you can choose the kind of input that will be processed. As mechanical as this may sound, you can't pursue your dreams and fulfill yourself at a deep level unless you participate in a rich, evolving, fully alive feedback loop.
A conscious lifestyle isn't divided, but integrated.
