Don’t worry about getting the perfect words down on the page/screen right away – just write.
Don’t worry about the laundry, or the dishes, or the toys all over the floor – just write.
Don’t worry about the plausibility of a police officer wearing her hair that way, or the kind of tomatoes that grow in Ontario in September – just write.
The extra research, the editing, the rewriting will come soon enough. Just enjoy the now and write.
(I should add that I shouldn’t worry about making it to the Twitter chats I’ve also recently discovered – ‘sup #writestuff – and just write, but tweeting counts as writing, right?)
