One of my New Year's resolutions is to blog more, especially after receiving some emails from people claiming that yes, y'all really DO read and recommend my blog! Puts the pressure on, but that's good. The brain needs to think.
And that's a key note for any creative endeavor: you have to refill the well. Some days I get so antsy with hitting a certain word count or spending so much time writing that the result isn't necessarily bad--it's just not as good as it could be.
Take time to breathe. Go walk around a town square or city avenue. Stroll under the glimmering high rises of the city or bask under a willowy tree in the country. Listen to music. Find new music, stuff you normally wouldn't even listen to. You might surprise yourself. Watch new films, devour looking at paintings, photographs, read books of all kinds--all of these things can speak to our souls, helping us refill the well.
And don't forget to never, ever quit!
