As I said at the time …
There’s no denying the importance for a writer to have a physical space where the work-in-progress can be left out in the open, safely behind a closed door, between sessions. Where there’s no lost time putting everything away, only to have to bring it out again in order to resume where one left off. This doesn’t have to be a dream space, either.
But making time for writing is even more crucial. Being able to get a thought or line down on paper, while it’s fresh. Of finding large blocks of time to engage in the interior dialogue of characters as they emerge amid your daily errands and nocturnal dreams. (Like babies or demons, they possess you.)
I’m not alone in finding my practice of writing becomes part of a larger juggling act, especially when I’m already working fifty-hour weeks as a professional whatever somewhere else. Especially when those hours are outside the “literary” field altogether. Then there are the needs of a home life to contend with, and, in my experience, a faith community, too. For instance, I’ve found that as long as I’m employed as a full-time journalist, my off-duty hours leave me only enough hours to (a) write and revise or (b) focus on submissions and correspondence or (c) attend and give readings and other public events; but there is no way to do two of the three (much less all three) in the same period.
On top of it all, the work takes as long as it needs. Or, like the old-house syndrome, every repair or renovation project will require at least three times more time and money than you budgeted.

Carry note books, even to just not down ideas that come into your mind throughout your day at your 9-5. Your passion is not that for which you do not have to work, or that for which the work doesn’t feel like work, but that for which you are willing to work – even when the work is grueling. Believe one day that you will write full time, and you will.

Yes, notebooks have been indispensable, even while driving. It’s amazing how many pieces emerge from a few words or sentences.
Another secret to writing I found is the importance of devoting one day a week to the work. For many years, when I was on a four-day week (which included a double shift on Saturday), I set Tuesdays aside as my writing-and-revision day. The novels and poetry volumes now appearing are products of that devotion.
