I never gave much thought to Groundhog Day until after I became a fan of the movie, starring Bill Murray. Since then, I always "celebrate" the day, which mostly means I am aware of it. It is a tradition with dubious origins and no real value from my perspective, other than providing an economic bump to a region of Pennsylvania.
There are lots of activities in organizations that are a bit like Groundhog day. We do them like clockwork, we aren't really sure why, and no one ever stops to look at the value these activities add.
Look at the traditions and rituals and established "this is how we do it heres" in your company, in your department and at your desk today. Determine if these things should continue, or be evaluated more closely for improvement or elimination.
It should be noted that many traditions are valuable and should be upheld, revered and strengthened. Perhaps you will find some of these in your search. If so, strengthen them, as they will strengthen your results.
I urge you then to make Groundhog Day matter - whether Phil sees his shadow or not.
p.s. When I was doing my radio show,
Magical Movies with Kevin Eikenberry, I did an hour on Groundhog Day. To listen, go to:
