When I decided to go weekly with my blog… November 2011? Looks like then… I chose Mondays as the day. Start of the week. It seemed like the best day to be sure that I could carve out an hour or two and write 1,000 words or so. After all, with the week just beginning, planning to write on Monday evening, you’re less prone to slippage, less prone to have your writing time suddenly filled with other, less fun, less meaningful-to-posterity things than if you set aside, say, 6 PM Wednesday.
