I stopped making specific resolutions, and started doing an 80/20 analysis of my year instead. There is a much more sophisticated version of this, but here is the practice from 10,000 feet:
Evaluate the last 12 months on your calendar thru the lens of: the 20% of people and activities that produced 80% of your positive / negative emotions
Commit to scheduling activities and appointments with people that bring you the positive 20%. This involves planning and paying for trips, planning meetings, get-togethers, and events now – or as early as possible.
Create a NOT-to-do list which includes people and activities you’ll avoid, as they represent the negative side of the list.
