"For some years after this I wrote very little, and nothing regularly, for publication: and great were the advantages which I derived from the intermission. It was of no common importance to me, at this period, to be able to digest and mature my thoughts for my own mind only, without any immediate call for giving them out in print. Had I gone on writing, it would have much disturbed the important transformation in my opinions and character, which took place during those years."

—John Stuart Mill, from Autobiography
