Elizabeth Gilbert, the recently famous author of "Eat, Pray, Love," has a very insightful, and funny, oratory on the creative process and writers in her February, 2009 TED Talk. What I found most profound about Elizabeth's talk was how accurately she described the creative process and the idea of a etherial being of some kind which helps to inspire and shape work.

While I don’t consider myself a “creative” by profession, I did earn an English degree in college, and I’m using it (thankfully) more than I anticipated. I guess this sort of puts me in that creative arena; creative writing and copywriting are definitely part of my role as corporate marketing manager.
That said, I go through phases of how I feel about my writing; some days I feel extremely confident about what I’ve written—be it web or email copy, or a client presentation.  Other days I feel like I have no business ever writing again. The latter is an extreme, and won’t ever happen, because I truly enjoy writing.
Often times, I use writing as a way to express emotion and think through issues in my personal life. Actual handwriting…typing is far from therapeutic. If I’m struggling with something, I write about it—free form, and most of the time, I feel much better after getting it down on paper. 
I do have a specific writing style and voice, and sometimes it’s challenging for me to step outside of those—but this is often necessary, especially as I write for different audiences and purposes.
I came across a couple of validating articles recently which helped me to see that perhaps my struggles are normal for writers.
