One last note about vocabulary learning: you will meet new words all the time in your textual explorations. Don’t pause and look up every word like this guy apparently does*, but rather try to figure out a rough meaning from context. If the word is important enough, you’ll see it again, and you’ll be able to sharpen the word’s meaning. The more you see the word, the sharper its meaning will become, and eventually you’ll know it without having to pause at all.
That’s just one of the benefits of reading both deeply and widely.
*The article says that reading with book in one hand and dictionary in the other is an “old English major’s habit.” As an old English major myself, I can say that this is not typical of the behavior of any English major I studied with.
