" Charles Spurgeon often preached ten times a week, preaching to an estimated ten million people during his lifetime. He usually preached from only one page of notes, and often from just an outline. He read about six books each week. During his lifetime, he had read The Pilgrim’s Progress through more than one hundred times. When he died, his personal library consisted of more than 12,000 books.
