I had a job for about a couple of years that gave me enough spare time to read Proust's 1.2m word epic In Search of Lost Time. There was some work to be done but it never took me more than an hour or two, and then my boss was quite happy for me to drift off to the Belle Epoque. I couldn't really get into reading it at home because, as the father of young kids, I was too busy most of the time and you really need to concentrate on P's page-long sentences. I alternated between leisurely, engrossed reading and teaching myself web development skills...happy days!
At the same Not that I consider reading Proust a waste of time,
