If you consciously walk a tightrope, you have no choice but to be aware. If your intellect is constantly choosing between good and bad, it has become a prejudiced intellect. And when it is busy sorting the world into good and bad, you will most definitely fall off the tightrope.
Don’t take the tightrope literally. You could just try bringing a certain precision into the physical movements of the body. (If you have a hatha yoga practice, it should happen anyway).
For instance, if you see a straight line on the floor, try walking in perfect alignment with that line, maintaining an easy gait. This is not about becoming self-conscious, but about becoming precise into every movement, every gesture. This is one way of dipping your intellect in awareness.
