“A goal is a dream with a deadline.” (By reading online, this may have first been said by Napoleon Hill, but it’s been attributed to others, too.)
All of your dreams and ideas need deadlines. “Best by” dates so you can plan, test, evaluate, and decide what’s after that.
Without deadlines there can be no priorities.
Dreams can expire, you know.
(h/t to my pal Rob for the kernel of this idea)
