I am currently reading the series of “A Song of Ice and Fire” and for someone who has a job, is on a swim team, goes to other activities over the weekends… I promise you that I will most probably finish the series when I graduate from high school, or maybe later.
I think the best way to plan your reading times is to find the purpose of you reading the book; some people read books about today`s world, the politics the ups and downs, the economy, well I think in this case to read before going to sleep maybe for 30 minutes or so is the best solution. Why? because usually people who have these interests in books are grown men and women who are involved in the outside world, so their typical day will most probably be to wake up in the early morning, have a cup of coffee, send their kids to school, go to work, come back, have dinner get into their bed, and they just want to learn something new about the world that they live in and sleep.
As for me, I read cause I war, alliance, traitors, and all the other dramas that happen in the fantasy world of my books. So usually I read whenever I feel like it, cause I`m not going to learn anything, I will not necessarily remember entirely what happened the last time I read but I know the atmosphere so I just have fun.
