In a way I'm lucky that all the writing I do doesn't have any deadlines. This means I can write when I feel like it and I can set my own rhythm. I do however set myself a wordcount target because I do need a bit of pushing and it forces me to get into a routine. I usually stick to my targets and make sure I write every day, otherwise I get a bit lazy.
However, as I hear authors rushing to meet their deadlines and having to write 4000 words a day to reach them, I wonder if the pressure dampens the joy of writing for them. I often find myself smiling as I write because I'm enjoying it and I have time to relish in the process knowing I don't have to finish it by a certain date and there is no axe over my head when I don't write because I want to think the scene out at a leisurely pace.
After all, not being published, has to have some benefits.
Do you need pressure to write? Do you feel happy when you write or do you see it as an obligation?
