It's not about finding time to write... at least, not for me. Because my writing-supporting job is teaching, I have two months of free-and-clear writing time each summer where, if I chose to do so, I could write for full 8 hour days if I chose.
But I don't.
Why? I don't really know. Maybe it's the perfectionist in me. Some people advise to write every day, even if what you're writing is horrible. I can't stomach that. Forcing myself to write because "it's time to write" is about as palatable as forcing myself to eat because "it's time to eat." If I'm not hungry, I don't want to eat. If the words aren't there, I don't want to write.
So how does one fill in that blank? Finding that... something... to write? Finding the spirit to write? The story to write? The words to write? All of those seem reasonable to me. Without them, writing is bland and colorless. I wish I knew how other writers, prolific writers, do it - get their ideas, keep the words flowing. I can't even keep my blog updated, for crying out loud!
So... does this make me less of a writer, knowing this? I surely hope not.
