I've started using this in conjunction with another productivity activity every morning. Let me tell you, this is a great tip. I've created a separate calendar in Google Calendar to track my progress. See, I have a backlog of book reviews that I've been fretting about for YEARS. I've fought and fought with trying to get the accomplished, and finding the right time to do them. With this tip, coupled with working on them as the first thing I do when I get up, I've found a HUGE productivity boost. I've already finished two reviews off of my list, whereas before they would have been caught up in my post-work cool-down. If you need a little productivity boost in your day, check this out. Remember- Don't break the chain!
