Wisdom can only be experienced.
Unlike knowledge which can be taught. We can learn as much knowledge as we want, but if we never went outside of the books we will not find the feelings of all senses. We will not know what is sweet, what is bitter, and so is in our heart. We might be able to learn how to make a guy or girl fall in love with us from all kinds of books or TVs. but we will never actually understand the heart break, the exciting and the happiness. To understand all these feelings we have to experiencing them, and then we learn, and there we grow.
Feeling and emotion is describable and imaginable in our head, but no, not with our heart.
