No, I have to have two on the go at all times. That's how I do it. One novel or memoir, and one book of non-fiction - usually one on business or writing or personal development. (The latter being an incredibly vague descriptor for a genre. Some are total mindset books that lead you to take action, some are totally practical books that attempt to alter your mindset through method, some rely on spirituality - the variants are seemingly endless.)
The main thing is that I don't attempt to juggle two stories at the same time. Anecdotal stuff in a non-fiction book is fine - it can help to illustrate a point - but I prefer not to mix the stories up in my head while reading them.
Here's how I do it:
The story I'm reading - at this moment in time, It's Kind of a Funny Story, is reserved for my lunch breaks in work, and bus journeys, when I'm not too tired to read. When I start college, that guarantees me two hours of reading per week, when I'll only work weekends. That's a minimum, because I'll probably make more of an effort to read on the bus when I love the extra day in work for reading.
I use this time for reading stories because I enjoy the escape, and I like to unwind with them. But there's another reason, and it's why I read the non-fiction books at home, in my personal time and space - I don't feel like I'm wasting time by reading non-fiction at home.
Let me clarify - fiction is not a waste of time. But when I'm at home, I'm presented with an option - my fiction, or someone else's. It's a better use of my time when I use it for (a) writing or (b) developing myself, my writing knowledge, or my business knowledge.
When I read non-fiction, my current book being Get Sh*t Done! by Niall Harbison, I think of it as investing my time in learning something important. In the case of my current read, it's using someone else's life lessons to develop a means towards living the life that I want - not the life other people want for me.
That's a different lesson to the previous book on my list - Creativity Inc. - which shed some light on how to run a creative business. This was, of course, in the context of a company with employees, and not a solo operation. However, there's something to remember here, about education and learning: while authors and teachers have their own intended learning outcomes, students may come out of the experience learning something else. In my case, how to better work on a creative team.
Why is that important? Well, my college course will require a lot of creative work with other people, people from different backgrounds, people I haven't even met before.
Do I have a book on how to better improve my people skills before then? Yes. Of course I do. I also have a book on how to feel more alive, one on dealing with change, one of being more effective, and one on public speaking - just in case I need to make a presentation. Those lessons are all valuable uses of my time, and I wouldn't be surprised if I found myself dedicating a lot more time than usual to reading them in an effort to draw some inspiration before my course begins.
But I won't just be reading those books. I'll be juggling some stories, like Maureen Johnson's The Last Little Blue Envelope, or Josh Sundquist's Just Don't Fall, or David Levithan's How They Met, or Darren Shan's Zom-B Clans - that's one novel on love and growing up and stuff, one memoir on growing up (with, and then without, cancer), one collection of short stories, and one zombie novel. Those are just the ones I think I can finish before college, comfortably, before I tackle Clash of Kings by George RR Martin.
This type of reading isn't sustainable, of course. There will come a time when I'll be forced to choose one or the other - and switching between the two as it suits me - because I'll have to read specific titles for college. But, while it's an option, it's the best one for me. Diversity in reading is important, and when I see people purposely choosing to avoid books that (a) have a story or (b) don't, I wonder if they've ever really given it a shot. I like to learn something new, and usually about something I wouldn't ever study in school or college (because, frankly, I don't think it's possible to grade somebody on something like personal growth), and I like to expose myself to new stories all the time.
Stories help us to develop a sense of empathy and understanding. That's one type of valuable lesson, and it's why I still write fiction when the truth of it has been revealed (the truth being that it's very difficult to make a living from writing fiction) - I believe that people can get something from reading lots of different types of stories, and that the exposure to new ideas and new people (albeit fictional ones) allows us to live a more open life.
At the same time, I believe that if we want to change our lives, we should. Society has this weird stigma attached to being different, and even when so many people read what are broadly described as "personal development" or "self-help" books, many people still look at them and wonder why they're reading something like that. (I used to. I'm speaking from experience here. My perception changed when I realised that I needed to.) Why do personal development books matter? Why should people care about what different people have to say about how to live life, or be happy, or run a business? Because we all live different lives and we can all learn from each other.
If you don't know how to escape the 9-5 job, someone else has probably already written a book about it. If you don't know how to influence people towards your way of thinking, someone else can probably explain how they do it. If you don't know how to do more with your life that you actually want to do, someone has probably written a book about it. (In fact, books do exist on those three topics - The Four Hour Work-Week, How to Win Friends and Influence People, and Get Sh*t Done! being the prime examples!)
I'm a reader, and while I still have the option, I'm going to continue taking on two books at a time. I'm not doing it because I think it'll make me a better person - I can change as a person, if I follow the lessons in the book, not just by reading it - but because it makes me a happier person. Reading is a pleasure, and whether I'm learning something new, or meeting new characters, I'll always find joy in a book (or two.)
