Blogging Vs. Writing

So, my friend, Carole -- who is also a writer -- twittered something yesterday that I absolutely agree with...
She was talking to a friend of ours (Donna Frank) who has written several books.
She mentioned to Donna that she had not written on her book lately, but that she had been doing a lot of blogging.
Donna responded with:
"Well, yeah, blogging is instant gratification. Sitting down and writing your book isn't; it's work and very delayed gratification."
What a profound truth!
In the past, when I was blogging more faithfully, I really struggled to make time for my book. There was this constant (albeit, imagined) pressure to post here, regularly and often.
When I recommitted to finishing the task God has given me (now, TWO books!), I found it harder and harder to come here and blog.
I couldn't figure it out at first, but there was an uneasy suspicion that I was somehow "cheating" on my book by blogging.
Now, that might sound weird if you are not a writer, but it's true!

Time issues aside, I found that I became more and more possessive of my analogies, stories, and musings. If something was really good, it would go in the book. How could I put it here?
There's always a fear that something you write will be stolen or misused and there's a deeper fear that you will "waste" all your good stuff on the blog.
So, what happened was I would go weeks without posting or I found myself alternately writing either really preachy stuff or "fluffy" stuff (which I loathe, by the way) here on my blog. I wasn't just selling myself short; I was selling you -- the reader -- short.

Carole has blogged about this struggle as well.

Yeah, I know; I'm totally neurotic to be obsessing about this, but to hear another writer (published author, no less!) surmise it so well was somehow comforting to me.
So, I can either focus my time on the calling God has placed on my life (my writing/my books) or I can worry about what other people think about my blogging.
Truthfully, I think it's a no-brainer. ;)
