I see similarities in that both a goal and a project are outcome driven and both can be checked off when they are done.
Is the only difference in the terms a matter of how long it takes to complete?
If I planned to retire in January 2015, does my goal become a project in january 2014 just by virtue of the calendar or is there some other factor?
If I had that as a goal, it would drive projects related to finances, health care, activity in retirement, et cetera. A 30,000 foot goal has a horizon of perhaps 1-2 years and drives projects, so it's a 30K goal.
