Drawing a “Line in the ground” depends on one’s geography and how deep it really is. For, the commitment to “stay the course” may only be if that course is not near any water way to wash it away. One might take such a strong stance but only have the duration of a nearby tide. Therefore, in the end make sure your lines are drawn deep enough for any rainfall to fall or watch another value of yours disappear.
FOOTNOTE- Red lines should be drawn indelible ink.
