Every now and then you run across a gem of a statement on Twitter. A few weeks ago, fantasy author @BrianRathbone tweeted the following: Writing is the art of claiming time and avoiding distraction.
I don't think I've ever heard what writing--in terms of life, really is--summed up so succinctly. The vast majority of people who love to write, who in fact do write novels, screenplays, poetry, etc., don't make a living at it, so they have to find time in between commutes, work, grocery shopping, reading, spending time with others, and general life. The actual small amount of time one gets to write in a day is very precious.
For most serious writers, being distraction-free is a must, if one wants to get anything accomplished of any decent level of quality. It's the same as if you're working out complex mathematical formulas in your head: being able to focus is key. Your story is a puzzle, and you're constantly searching for the correct next piece.
Some non-distinct grey noise in the background can be beneficial (coffee shops are great), but anything that is very distinct, and specifically targeted directly at you, makes it all but impossible to complete the task at hand.
Some people don't seem to understand (a) how strongly distraction negatively affects a writer & (b) how precious the short amount of time one has to write really is. I think many people don't have the desire to try to be exceptional to the world in any way (or the desire to put out the monstrous amount of effort required to be exceptional), and for some of those people, doing whatever is necessary to not be bored in the current fleeting moment is on the forefront of their minds, constantly, just like with puppies.
When these puppy-people distract you, especially when they distract you often, for no other purpose but to express some banality of the moment, so that they're not bored--they are taking away something from you that is precious.
And you just want to take a rolled-up piece of newspaper and smack them over the head, and say "Bad puppy!"
