This is the way to learn grammar.

From Emerson's "American Scholar" (sorry for the masculine language... but I think the message transcends such biggotry) :

"Books are the best of things, well used; abused, among the worst. What is the right use? What is the one end which all means go to effect? They are for nothing but to inspire. I had better never see a book than to be warped by its attraction clean out of my own orbit, and made a satellite instead of a system. The one thing in the world, of value, is the active soul. This every man is entitled to; this every man contains within him, although in almost all men obstructed and as yet unborn. The soul active sees absolute truth and utters truth, or creates. In this action it is progressive. The book, the college, the school of art, the institution of any kind, stop with some past utterance of genius. This is good, say they, --let us hold by this. They pin me down. They look backward and not forward. But genius looks forward: the eyes of man are set in his forhead, not in his hindhead: man hopes: genius creates. Whatever talents may be, if the man create not, the pure efflux if the Deity is not his; --cinders and smoke there may be, but not yet flame. There are creative manners, there are creative actions, and creative words; manners, actions, words, that is, indicative of no custom or authority, but springing spontaneous from the mind's own sense of good and fair....

...Undoubtedly there is a right way of reading, so it be sternly subordinated. Man Thinking must not be subdued by his instruments. Books are for the scholar's idle times. When we can read God directly, the hour is too precious to be wasted in other men's transcrips of their readings. But when the intervals of darkness come, as come they must,-- when the sun is hid and the stars withdraw their shining,-- we repair to the lamps which were kindled by their ray, to guide our steps to the East again, where the dawn is. We hear, that we may speak. The Arabian proverb says, "A fig tree, looking on a fig tree, becometh fruitful."
