I really don't.
I'm rubbish when I have a lot of time. Endless time means endless ways to put things off. Far better is to snatch 10 minutes here or there and start writing before I have time to worry about it. Often the first page is not good, but I kind of warm up into it. I don't let myself faff on with it all.
The only drawback with this is that I'm doing it all longhand, and I do actually need some time to type it up/edit. This is where more hours in the day would definitely come in handy. Especially because I seem to have lots of new ideas percolating away, but until I actually make a start on one of them, they're a bit pointless. One of my many bad writing habits is to plan an entire play/novel/film trilogy in my head, decide it's brilliant and not actually write a single word of it down on paper.
So I'm trying to avoid that.
