It has been said that what gets measured gets done.
How can you take this further and celebrate what gets done?
I have a FitBit fitness tracker, and by the mere measuring of my steps, I am far more likely to walk 10,000/day. Oftentimes I make one final effort to get those last steps in so I hit the goal and get my smiley face.
This week I received my Japan Badge, telling me I walked 1,869 miles in my (FitBit) lifetime, the length of Japan! I did not know this was a milestone; I was not working explicitly toward it, yet it brought a smile that I had achieved it.
It is the same technique as the gold stars in grade school; internal motivation is fine, but it is kickstarted by that motivation to get the external evidence.
