Do I not have enough time to write? Or do I tell myself I don't have enough time to write?
Convincing myself I don't have time to write is like a reverse-psychology procrastination method. Yes, writing in 10-15 minute spurts is not ideal, but we don't live in an ideal world. A writer writes. Period. End of sentence. I've read about lots of aspiring authors who write while waiting to pick their kids up from school, in the waiting room, in traffic. They may only have 5 minutes, but they do it. Two nights ago, I was cooking dinner, still had not written. But I had 10 minutes left until my food was ready. And I decided to find out what I could accomplish in those 600 seconds. Surprisingly, a lot! Maybe not as much as I could in 2 hours, but more than I assumed. In fact, because I had limited time, I didn't have time to waste to "get into writing mode." Even though my actual writing time was short, those 10 minutes got my creative wheels spinning so that when I returned to my WIP later that night, I could jump in where I left off. It's like exercise - even a few minutes a day of it has beneficial effects for hours afterwards.
When you think about it, if you add up all those 5-10 sessions during a day, you come out with some decent writing time. And when you publish your novel and people ask how you managed to do it between job/family/other, you can say with a smile "Oh, I just wrote a few minutes here on the train, a few minutes there in the doctor waiting room, and whalla! I had a novel!"
What is the shortest amount of time you've had to write and where were you?
