I believe that it was Thomas Edison who said, "Many of life's failures are people who did not realize how close they were to success when they gave up." 

"A word to the wise." Wise, intelligent people need no additional fluff or elaboration.

If you are presently engaged in an initiative, thinking of quitting and turning your attention and focus elsewhere….

Before you do, please counsel your inner circle. Get some additional perspective before you finally throw in the towel. Maybe the bounty of your harvest is just around the bend. (Besides, your inner circle may see something about the situation from an outside perspective or a blind spot for you that might be helpful– it takes little additional effort beyond the ask.)

Just a thought.
