Not GP, but I'll relate my experience. Your attention is always automatically attending to something. You can learn to attend to your attention continually while you're functioning normally in real life. Maintaining this light noticing of what we're noticing, reveals the attitudes of the mind to various objects as we go through our lives. It's a very interesting state to abide in. This is known as the Cittanupassana practice, one of the Vipassana practices described in the Satipatthana Sutta.
