I get this question frequently and it came up at book group last night. I explained that I always have a book with me, read while I do mundane activities like blow drying my hair, etc.
But I forgot the biggest thing. I don't watch TV. I have watched less than 20 hours of TV this year, and that includes several nights of Gilmore Girls episodes while Bethany was here visiting. I stream Downton Abbey and Project Runway, usually while I'm fixing dinner.
I don't play computer games any more. I don't watch movies, except on very rare occasions as a family activity.
I used to watch a lot of TV. I used to play a lot of computer games. I didn't make a conscious decision to stop, but we got rid of our satellite a year ago and have not missed it. I didn't decide to stop playing computer games; I just don't really enjoy them any more.
I used to lose a lot of time to Facebook and websurfing, but I gave up on trying to keep up with every bit of news from everyone that I know. Now I check in briefly several times a day. I don't just go looking to see if I can find something to read. I check specific sites and then get off.
If I want to relax, I read a book. And I do read quickly. That's how I read so many books.
