When I happen to be stretched for time, I have a tendency to break everything; including writing, into manageable chunks, so that I can function at the level I need to. When I do this, I also rarely get bored. And honestly? I am always stretched for time. It can take me days to write one of my more epic blog columns. I enjoy this a whole lot more than trying to crank out a post a day, or several posts a day, as I see some people doing. I have no idea how they have the time or inclination to do something like that, and rarely is their material very good, because quantity takes quality's place.
What are you left with then?
And, who has time to read everything, anyway? I say, choose your words carefully, so they will be effective enough to make your readers think. Less is usually more, so when you are working on something, keep that in mind.
That is not to say I don't wax loquacious at times. I can be mighty wordy. But usually, it's because I either honestly do have a lot to say, or it's because I have a lot of things to relate to what's been said.
So, when pressed for time, that's what I do. What can be very nice about writing this way, is that you don't get sick of the particular piece you are working on. If you can keep the subject matter on your mind, and make little notes here and there; adding them when you come back to your piece, it can be quite inspired. Rarely, do I think of everything that goes into one of my columns in one go.
Of course, in the here and now, that is not really what I'm doing, since I am trying to write on a different subject every day, and actually turn out a piece every day. Pieces are bound to be shorter. Because, like I said, I am always stretched for time.
