When famous tech people like Bill Gates post lists of books, there is almost never any fiction on there.
It's like reading is frowned upon as a waste of time unless it's non-fiction. You can get away with literary fiction but only if it's high-brow enough that it still feels like learning.
Can I not just read a fantasy book because I find it entertaining?
Read more, worry less about what others think. I read an average of a book a week (and I'm a slow reader), and most people find that to be argument enough to read whatever I want.
I strongly prefer actual books, but I've been doing a lot of reading on my iphone over the past few years due to being able to read when I have spots of downtime (waiting on oil change, for example).
That sounds like a feature, not a bug to me.
> To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence. And in childhood and adolescence they are, in moderation, healthy symptoms. Young things ought to want to grow. But to carry on into middle life or even into early manhood this concern about being adult is a mark of really arrested development. When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.
