writethisfanfic | WIP Challenge Check-in, Day 23 -- Thursday (Reply)

It's Thursday and that means the weekend is almost here! I hope it's been a good day for you, whether you got any writing done or not. Here's the thought-provoking quote for the day:

If a writer knows enough about what he is writing about, he may omit things that he knows.
The dignity of movement of an iceberg is due to only one ninth of it being above water.
~~ Ernest Hemingway

How did your writing go today?

I actually wrote
I did research
I did editing
I posted
I took a break
I'm still staring at the page trying get started
I had too much Real Life stuff to deal with and couldn't think about writing

For discussion: I have found it true that a lot of the research I do to create a body of knowledge about what I am writing doesn't always get used when I actually start writing, yet the fact that I researched and know the subject matter still seems to give me a foundation which is somehow revealed in the story, even if I'm not writing about it in detail. That's why I chose the above quote for today! Do you find this to be true as well, or not? Are details important for you to include when you write or are they not so important?
