I've only just seen this thread, but I decided to do this a few weeks ago, and it's already really paying off - I'm finally making some progress with my UFOs and am following Leah Day's Quilt Along, where I'm learning so much. My promise to myself was an hour a day to do something creative (I have the luxury of the hour because I'm retired and live alone). It's given priority - if I have a busy day, and can't get through all my usual routines, this is the one thing I'll try to get done. I'm also putting more on my blog, and lots of ideas are sparking in my brain. I've been told for years that if I'm serious about creativity, I have to do something every day, and it does seem to be true. I feel so much better for spending more time sewing and writing, and there's a great sense of achievement.
