Goals for new story

One of the main goals that I'm working towards for my new tale is to change the perception in regards to actual 'Hauntings'. The superficial views in regards to the subject usually revolve around seeing transparent figures, Poltergeist activity, maybe even  hearing phantom voices and footsteps. While such views definitely deserve recognition, I want to show that a negative entity can affect lives in other ways as well. Tragedy, grief, loss, relationship problems, financial disasters, and health issues can also be attributed and there have been several instances where people residing in disturbed properties have reported going through them. With that angle, when considering the paranormal, concerns should be broadened.
I also want a clear juxtaposition between the differences of a house that is disturbed by 'Ghosts' and one that is disturbed by an Entity. Ghosts are the remaining energies of dead people, they can longer interact with the living, make cognizant decisions and so forth. An Entity is not what I'd consider Human, therefore they are not limited by human capabilities. Their abilities go much further beyond explanation.

How to measure progress?

I find it sometimes strange when I consider what most people recognize as progress. I mean, I personally have had fits of writers block that could last months. So, that being said, if you are able to have a decent output of material over an acceptable time frame, I wouldn't consider it a bad thing. I recently read about a writer whose blocks were so severe that it literally took him over two decades to complete one particular novel. Considering the fact that I haven't even been writing that long, such a situation would have definitely affected me.
But, how long is such an acceptable period? When one decides what sort of tale their going to weave, be it a Novel, Novella, or short story, the best way I feel one can measure progress is how much work one spends on it daily. I feel, to truly consider yourself a writer, you have to spend at least two hours daily if not just writing, then also brainstorming , researching, and otherwise.
Like everything else in life, I believe that writing is most definitely something that you will get out of what you put into it.

New story to be based on actual Entity

In 1962 a man by the name of Joseph Morse bludgeoned his mother and invalid sister to death in a rural home in Chula Vista. In 1964, Raymond Goedecke jr killed both of his parents and siblings in a similar fashion in the same city. While these tragic slayings were

seemingly unrelated, a tiny bit of research would show that they happened on the same area where the house that I grew up in was built.
It's ironic that I usually take the instances 'Based on a true story' or 'Inspired by true events' with a grain of salt thanks to movies like 'The Amityville Horror' and others, I can honestly say(after years of downplaying it)that I grew up in a house that was possessed by an entity.
With that said, and all of the pain and tragedy that came with that kind of scenario, I'm finally ready to write a story based upon my experiences there. Of course there are going to be changes to names and circumstances but the overall concept will stay the same.
I'm calling this new tale 'Deimos Phobos' in homage to the Greek twin gods born of the war god Ares and Aphrodite and that those two represent everything I felt in my, and my families', thirty year time frame in that house.
'Fear' and 'Dread'.
