Books have been making a real comeback in recent years and the how or why it's occuring is of no concern because I'm just thrillled it's happening. As someone who made it his mission to get his grade eight students to just read a book, I'm here for it.
However, I want to provide some reassurance to those picking up this hobby because listening to some of the elitism around it can be discouraging.
First, there is no line between "real" literature and the "rest." That's an imaginary line created by others who demand more from their reading and want to make themselves feel better about their self-inflicted suffering for it.
On that note, you don't have to read the classics. They can be great if you're interested, but they're about as necessary as learning Latin. Those who tell me that literature stopped at James Joyce might as well join the camp of Catholics who proclaim that philosophy stopped at Aquinas.
It's okay to like a book that others hated. I'm certain you like food that others hate as well, but that shouldn't stop you from enjoying it.
The flip side is it's okay to hate a book that others have liked/loved/made popular.
It's okay to enjoy books that offer nothing more than fun escapism. Life can be challenging enough as it is, and tomorrow isn't guaranteed to any of us, so take whatever relaxing joy you can.
Your aim should be consistency, not speed. It really doesn't matter how long it takes you to read a book as long as you're consistently reading. That's how habits are built.
Graphic novels count as books.
You don't have to read certain books and it's okay to not finish a book if it's just not working out for you. There's an infinite number of books out there and more being published every year, so just read whatever catches your interest.
The only distinction between hard copies and ebooks is personal preference (the one exception is reading digital books on your phone while you still have notifications enabled). Audiobooks engage a different part of the brain, but do not diminish your enjoyment of literature if that's the medium you like.
Every so often, head down to your local library and just wander through the stacks. No algorithm can offer you the serendipity of finding a random book that might just become your next favourite.
Finally, you don't need large swaths of time to read a few lines here and there. Don't make this bigger than it needs to be. Case in point, I worked on an automtive assembly line and would read a few lines in-between cars. The person who taught me this was the guy who worked behind me and threatened me with a tire iron if I didn't start reading so my brain wouldn't turn to mush working there. I can't thank him enough.
Simply put, if you want to read—just read.
