That's called learning how to meditate. And yes, it works wonders with cognitive ability and control of cognitive ability.
The standard efficient process of learning how to meditate is:
Focus attention somewhere for as long as possible.
Move focused attention around from subject to subject, including inside your own body.
Spread your attention outward from the focused point, making sure to maintain attention on the focused point.
Scan your body. Just become aware of everything you observe when scanning; don't try to change anything.
Can I focus my attention on my attention and get compounding results? :)
