Especially these days, when time can flow by unmarked in a way we have never experienced before, I worry when people say, “I can only write at such-and-such a time”. Yes, it’s always good to have a routine to give yourself a boost. But you can’t write at any other time? Really?
My worry is that any hard-and-fast rule we can come up with about writing is manna to the Inner Critic. Of course you can write any time of the day or night. The writing may look different then, but is that such a bad thing?
Experiment. Stay curious. And remember (to borrow from Ed Lawrence, CBC Radio’s gardening guru, who says “The best time to prune is when you have the secateurs in your hand”): the best time to write is when you have some time. End of story.
