You must get into the habit of looking intensely at words, and assuring yourself of their meaning, syllable by syllable-nay, letter by letter... you might read all the books in the British Museum (if you could live long enough) and remain an utterly "illiterate," undeducated person; but if you read ten pages of a good book, letter by letter, - that is to say, with real accuracy- you are for evermore in some measure an educated person.
