As to the research: yes and no? As an ex-academic, I'm used to buttloads of research just to write a 20 page paper. In comparison with that, the research for this book, in terms of numbers of sources, was low. In terms of years of dealing with my own Fears, and those of others, studying military history (war), I've spent decades on it.
Faces of Fear? Infinite, is the easy answer. I didn't try to enumerate them all. That would take a thousand years, and replicate what clinical psychologists have been doing for 100 years. My goal was to un-explain Fear, to take it from the complex to the simple, if possible. I think I've accomplished it.
In the book, I use a metaphor of the Tree of Fear.
At the top are the Fruits: all of our daily, projected, or imagined Fears (failure, chaos, loss, stage fright, you name it). To group those into smaller categories, I used Brendon Burchard's three: the Fears of the Pain of Loss, Pain of Process, and Pain of Outcome. All of our modern, daily Fears fall into one of those three. They are the Branches of the Tree, if you will.
Below that is the Trunk of the Tree: what I call the Known Fears.
Known Fears can be from any category, but we are at least vaguely aware of them, if we think about it for a few minutes. They usually stem from some past negative experience that we remember.
Under the surface, are the Roots of the Tree: what I call Unknown Fears. They are subconscious. We don't really remember them anymore. They are still there, however, and since they're subconscious, wield a crapload of power over us.
As to how I figured them out, the Branches are from coach Brendon Burchard, which he talks about in a video I saw on YouTube. I also mention the categories put forward by Napoleon Hill, almost a hundred years ago, in his Think and Grow Rich, book. Both of them left out the Known and Unknown, for some reason. I reasoned those out.
There is a Seed of the Tree, but you're gonna have to read the book for that one
I should mention, that the book goes live on Amazon, on Dec 11th. And it will be FREE for the first 2 days!
