I'm predisposed to think that as a people, we're hardwired to understand things through the telling of stories. I think that as human beings it's part of who we are.
I've learned that I get blocked when my subconscious mind is telling me that I've taken the work in a wrong direction, and that once I start listening to what my subconscious is trying to tell me, I can work out the problem and get moving again.
