Slow reading to enjoy more but how?

In the fast world where success is measured by the productivity, how to slow down the reading literature to enjoy more? Are we not overwhelmed by the people on the internet when they share in post, video that they read so many books in a week, month or year?

Do you have figured out how to stay away from all noises and immerse completely into reading?

I would like to read In search of lost time, The Tale of Genji or The Gormenghast trilogy without having a deadline on time - but then I think that would be impossible. But life is short - time is limited.
