It's odd, I know. I disliked school immensely when I was in it. They never seemed to delve into any areas of history or art, or creativity that I enjoyed. I'm not alone, I don't think, because it seems to me many artists had the same attitude about school. I do wish now that I had studied harder because many things link to others. But it's also fun learning it all now.
After I graduated, I discovered I could study into all the things no one touched in the classroom. And I found quite fascinating topics from philosophy of religions to world mysteries and psychotic psychologies. Researching these topics is a healthy boost to my imagination.
Druids seem to pop up in many areas of what I'm researching for my latest novel, Among the Ancients (http://amongtheancients.tcmcmullen.com) along with Paganism. It's interesting to ponder how different the world would be today had Paganism stayed prominent - if the ancient religions hadn't vanished. I don't claim to be an expert, far from it, but I have woven what I know into the fibers of my next book to create that possible world even more so than I did in my Manipulated Evil Trilogy (www.manipulatedevilseries.com).
I'm still studying, even as I write, and hope that the flavor of my stories improves with each new thing I discover.
