Here's the scenario:
You have just been visited by an angel. The angel told you that your mission on earth is almost over, that you'll be called home soon. The angel told you that you will meet a stranger that needs guidance, and you will have a chance to tell that stranger one thing that will help them all their life. You want to crown your time here with a golden nugget that makes that stranger's life better over the long haul, whether they understand it right now or not.
A mind warrior should enjoy thinking and a good thought challenge, so what would your advice be to this stranger?
