By using it purposefully to achieve something you think is important.
A good example comes from the use of sensing. Development of sensing
provides a direct and keen awareness of physical realities and excellent
powers of observation. If you are sitting on a train, watching the
scenery go by, you are using your sensing but not particularly developing
it. If you are driving yourself around a strange city, you will
probably concentrate your sensing to notice and remember landmarks
this process develops your sensing. Of course, this kind
of focus and effort requires both perception and judgment, the dominant
helping the auxiliary to develop, and vice versa.
