When you’re stuck in a black hole where it’s impossible for you to reach escape velocity, your only hope for escape is to find an even stronger gravitational field to pull you out. People act a lot like gravitational fields, and when you put enough of them together, all tugging at you in a consistent direction, you’re going to move.
This is a vastly better version of the old adage, “you are the average of your five closest friends.” I very intentionally use the people I find and train with in the Art du Dèplacement universe in this way. (Semantic detour: I may have you plotted in the ADD space even if you would say you are in some other.) If I’ve trained with you, you now know why I am sincerely appreciative of _your_ contribution to my journey.
