I have followed various "productivity" systems over the past few years. Get It Done, note taking, to do lists, tracking progress, measuring each step are all tenets of "productivity." I find that these systems are all well and good for those of us who just need a kick in the right direction, but there are many downsides. You get so caught up in measuring your progress, completing tasks, making gains and so forth. All of those phrases could be put in quotation marks, because what is "progress?" Also, what good is completing tasks and making gains if they don't matter.
This post is the opposite of the Negative Nancy first paragraph. I think its important to get away from productivity systems. People who are most efficient are those who are doing what they truly LOVE. For these people, they often don't need productivity systems, because they know exactly what they need and want to do. I think being passionate about what you are doing, and completing the tasks that you are most passionate about is the most effective productivity system.
When you stop worrying about measuring, tracking, completing and all these other tasks you can slow down and enjoy the moment. My advice: take a deep breath, and go do what you WANT to do.
