Books are a big part of who I am. Since I was a little girl, reading took up a large part of my day. I can't finish books at the speed I used to because I have adult things to do all day, but I still enjoy reading.
When I was in art school studying communication design and working in advertising and branding design, my books were more for research and inspiration since the worldwide web literally sucked back then.
Before collecting cameras, I was collecting books. I had a great variety of design books ranging from typography, marketing, logo or brand design to packaging design. I still have a few that I would gladly give away because I have no need for them. My collection now consists of Photography coffee table books, a select few science fiction, and fantasy novels. Those are my favorite.
Reading eBooks, magazines, articles and blog posts are great too but not something I like to do often. Not as much as reading a physical printed book.
Reading books can be a great source of inspiration. Once transported into a fictional world your brain is free to think of whatever creative block or writing block you're suffering from. Looking at images for inspiration, watching how-to videos and stalking other professional's social media is not going to work. Your brain needs to be free from the "pressure to create". You need to read a book, preferably a novel or fictional story. No images, no pictures, no instructional step by step bull.
