Learning bears fruit when it is applied. Wisdom, of course, can be pursued for its own sake: there is even a kind of beauty in it. But, truth told, one never really knows if he is wise or not until he sees the results of trying to apply it.
Any activity, skill or profession -- ditch digging, law, engineering, cooking or whatever -- no matter how well studied, collides at last with the acid test: can one DO it ? And that doing requires practice.
