I spend more time writing than I do at my pay-the-bills job (which, luckily, I enjoy), and there are times when I get on a writing jag and reading takes a back seat. I tell myself that I don't have time to read because I have a novel to finish. This can become a problem when I'm submerged in the creative process of writing (as opposed to the editing/revision stuff), because to be able to write, I must read.
When I don't read, my entire creative process suffers. My storyline begins to feel forced and I get writer's block and all that annoying psychological crap that makes writing - the thing I most enjoy doing - not so enjoyable. Reading is how I fill up, top off, put a flame to, however you want to think of it - my ability to create. I don't know why this is, I only know that it is. Someone told me recently that Stephen King spends four hours a day reading and four hours a day writing. I know exactly why he spends that amount of time reading. He's filling up.
On that note, I'm off to balance my writer-self by happily tackling the teetering stack on my nightstand (timely Amazon delivery today: Where She Went, Saving Francesca, Liar, After Ever After and Will Grayson, Will Grayson), plus all the stuff labeled New! on my Kindle.
