When I think of Groundhog Day, I think of Punxsutawney Phil, Bill Murray, and David Seah1.
Eight years ago, Dave wrote an article about Groundhog Day Resolutions, a creative way to follow up on your goals and New Year's resolutions each month:
Extending the pattern of dates, I hearby decree that the THIRD DAY of the THIRD MONTH, the FOURTH DAY of the FOURTH MONTH, and other dates with the same magical month/day pairing as days of GHD Resolution Review. That should be easy to remember for everyone, and the numerical pattern should work as a reasonably-good memory trigger.
Dave's productivity tools are beautiful if paper is your jam.
