This doesn't work for me. I've tried several times, but I just can't make it stick.
I set myself a target of writing one good blog post a week about a year ago, with the target of having 52 posts in a year. Right now, I have about 31 with 1 month to go - I am pretty pleased with that, especially since I have been on at least 4 weeks holidays through the year where I left my laptop firmly at home.
