Great scene from a really under rated movie, Don.
Welcome aboard, William. Mixing or forcing, is fine. I prefer allowing. Life things come up. And usually they rear their heads at the wrong time. I build in the time, to allow for those life moments. Last week, my landscaper showed up unannounced, with two tons of sand. I had to stop what I was writing, and go outside and remove about 50 pavers that had settled when heavy rains washed the sand off my backyard "beach" area. No big deal. I went out and took care of that life moment, the same as if my wife came into my office and asks me if I want to go for a walk. Because I have life built into my day, the answer is almost always yes.
Like you, I usually hit a bit higher than 1K words and if no life events pop up, I can take an extra day for myself now and then. Or, like this week, have the flexibility to move the schedule up a whole month, and kick it into overdrive to avoid having to tighten the budget.
We're each the skipper of our own vessels. If I run aground, I have only myself to blame. So, I plot a course to avoid the shallows and allow a little more depth under the keel just in case a foul wind blows.
