I neglected most TV and all newspapers ; I`m gradually working my way through a huge pile of newspapers ( mostly the arts sections of The Times, and just 3 Times news sections to read now, it`s about down to a 40cm pile ). I think the longest book was around 3 hours, so maybe 6 hours reading a day was needed. It is really doable, if you just focus on the books and have the incentive of reading by a certain date or losing access.
Plus, I read so many great books, that I rarely felt I was doing a forced read. I genuinely enjoyed picking up the Kindle to keep reading.
I`m starting a new list of Kindle Unlimited books which I`d like to read, and then will get a month`s access towards the end of 2018/beginning of 2019.
