Completely. It really applies to anything work oriented, but I can totally get more on the writing side.
Writing, especially pre-planned writing is difficult. Personally, I don't plan anything I write. I sit down, and write. If one of my current projects pops onto the page, then it does. Often times, I get a lot of raw writing resources I can work with, and I simply impliment those into the different places in my projects that it applies.
If you just do the 15 minutes of daily writing, you'll start to become a lot more fine-tuned as a writer. Every single day, sit down to either a pen/paper or the PC (Whichever you can do quicker) and write for 15-20 minutes. Don't stop writing at all. Don't think, just write. You can write whatever you want, as long as you don't stop. Disable spell check and all that crap: We're not writing for content. We're getting 15 minutes of pure thought flow. You don't pick up your pen/pause your fingertips. You don't hesitate, correct, or edit. If you absolutely have to, you use single line-thru's, and that's it. Also, don't stop yourself. If you're on a roll, you don't have to stop at 15 minutes. Don't repeatedly check the clock over and over again. Get the entirety of your ideas out, and once an idea dies, glance at a clock.
You don't do this in hopes you'll write masterpieces. About 1% of what I wrote in my first year of unprompted writing time is useful. The more you do it, however, the more useful writing comes out of it. That isn't why we do it, though. Once you become practiced at daily writing, when you sit down with intent, you find it easier to connect ideas, come up with ideas, and flesh out ideas. It's simply a method of creating a stronger connection from your brain to your paper.
Lets assume you already do daily writing. Good. Now you have to apply the same concept to your directive writing. You know you need to write about a character finding a place to live. Good. Maybe you know a few other key details about the section of writing. Lets say the place has a specific area, say an attic, that'll be important to the rest of the story. Good. Now sit down and write for 20 minutes. The exact same way you write in your daily writing, but this time, you'll have the prompt: Character finds a home.
Now you have a gigantic piece of raw untainted resource to chizzel and mold to your desires. Now it simply comes down to being an editor. You start general, and you get smaller. Same concept.
