When I joined SP in January 2011, I set all kinds of goals for myself, joined many different teams and subscribed to lots of blogs. I realized recently that I wasn't even trying to meet many of the goals, or joining any of the team challenges, so today I spent a couple of hours re-evaluating my use SP commitment. As a result, I reduced my teams to 5, which I will huddle with daily. I made realistic goals, which I will strive to meet daily/weekly. I un-subscribed from some blogs.
In other words, my committment is stronger, but the number of commitments is fewer. I believe that, for me, this is a better way to use SP. I feel freer already, and more in control.
