Here's confessions of someone who read 164: http://www.vox.com/2015/12/29/10634416/reading-list-books
Blogger/economist Tyler Cowan also advises quitting books that are a slog.
That's about right. I spend about 2-hours per week on television (depending on the season I spend zero) and I haven't played a video game in 5 years. There have been many times that I've wanted to see certain shows (Supergirl looked fun) but when the time comes reading wins out almost every time. I can only read this much because I love reading more than any other form of entertainment. It would be impossible otherwise. It does kinda stink to never be able to engage in conversations about games and shows though. Maybe there's a market for semi-annual books about current media. ;)
2 books per week was an amount that makes me happy, so I kept up with it easily. I fell behind early this year because my wife and I wanted to catch up on a couple of TV shows, which meant I needed to average over 2.5 books per week. That was enough to kill part of the fun, which is why I've struggled.
A goal is great because it helps you get started on the next book when you might want to do something easier. But if it's too big it just makes reading a chore.
