I used to read all the time, so much that I was going through books like a fiend. In high school, it was not unusual for me to finish a book a week, and I was a regular patron of the town library. Somewhere along the way, I lost that. My reading habits atrophied to mostly just comics and then eventually just the occasional graphic novel.
In the last few months, I reversed that. Of course, I'm still reading graphic novels - I just finished the collected edition of Greg Pak's "Planet Hulk" which was sadly disappointing - but I've read several novels and short story collections lately that I've quite enjoyed. And I've found that reading has enhanced my enjoyment of writing and vice versa.
Last night I ended up writing and then reading before bed, and it was a very fulfilling experience. I didn't get all that much done, but I felt the juices flowing. I was on, y'know? The words came easily, and then when I switched to reading - I'm in the middle of a fascinating novel called 'The Windup Girl' - even that just felt right. The fact that the book is good helps a lot, I'm sure.
