I am using my May Days to put a lot of time into one project, something I've done the last two May Days. The same project, I'm sorry to say. But, once again during this May Days I am experiencing the value of trying to write every day on the same project. It's incredibly helpful for organic writers like myself. We have trouble isolating plot and planning out what we're going to do for an entire story. We deal with stories as a whole organism. If we have to stay away from that organism too long, it takes us a while to come back up to speed, because while we have a feel for our whole story, we aren't good on the details that are coming up. It's hard for us to pick up where we left off.
The May Days project forces us to write every day. For me, this meant spending some time at my laptop in a motel room between biking excursions this past weekend. Writing every day increases chances of having a breakout experience (at least it increases my chances), and I had one on a bike the next day. This led to taking notes on it while having lunch in a sandwich shop (my work for the day) and that led to a much easier transition back to work on Monday.
Whenever I find myself in a situation where I'm writing every day, even a tiny amount, I think, I've got to keep this up! Not because I accomplish so much (I did mention that I've been working on the same May Days project three years in a row, right?) but because it keeps my head in the game.
That is a huge plus for time management.
