From  Breena Clarke author of River, Cross My Heart and Stand the Storm:

There is balance as a writer. It is a solitary profession in many respects. One thing that has been fortunate for me is that before my first book was published, I worked full time in an office and part time at my writing. After River, Cross My Heart, I was able to write full time. I do have a lot of buddies and friends, I’m married and I have my dogs. I have a nice little social circle, and when I was working full time, I used public transportation. Having contact with people, just looking at them and watching them, is a great asset. It’s interesting to try and read what they are thinking, seeing their faces and bodies and attitudes and being sketch out them as characters. I have continued to do that when I can. Now that writing full time, one thing that was most difficult was (took an early retirement) was the thought I could write all day. I thought how fabulous it would be, but it doesn’t work that way. No one works twenty-four-hours a day. It took me quite awhile to achieve a schedule. For the first time, I was in charge of my whole schedule.

From an interview with author, screenwriter, and television producer George Pelecanos:

It was at a point that many hardboiled detective novels were more about the WHY rather than the WHO. I had gone down there (with the police) and hung out and done the street work, and I saw a different possibility and changed direction. I look at it as a form of reporting and you have to feel the dirt between your fingers. I talk to people, and I listen. An afternoon of work can consist of walking into a bar and ordering a beer and listening to people talk, riding the bus down the avenue, or just getting outside and hanging out with people. What I try to do is to front load all my research – spend a couple of months being out there – with police, prison, parole officer, humane society officers. It’s part of the job. You have to get enough ammunition to write a book, then come home and lock yourself in for five or six months – day and night – and everything (due to my research) is there at my feet.

When you are researching, I keep it all in my head. It intimidates people when you pull out a pad or a tape recorder. Then, when you get home, you make your notes.

The trick now, is to take those observations and write them down into something substantial and cohesive.
