A handful of responses to this:
"A common quality I see of people who are successful is that they are voracious readers."
"Reading is the sole means by which we slip, involuntarily, often helplessly, into another’s skin, another’s voice, another’s soul."
"No matter how busy you may think you are, you must find time for reading, or surrender yourself to self-chosen ignorance."
"The more that you read, the more things you will know. The more you learn, the more places you’ll go!"
"The best advice I ever got was that knowledge is power and to keep reading."
"A reader lives a thousand lives before he dies . . . The man who never reads lives only one."
"Reading is essential for those who seek to rise above the ordinary."
"The person who deserves most pity is a lonesome one on a rainy day who doesn’t know how to read."
"There is nothing more luxurious than eating while you read—unless it be reading while you eat."
