If you were on a rowing team and one of the crew was rowing in the opposite direction of everyone else in the boat, and if after kind and reasonable discussion gave way to arguing and non-movement, there is only one thing to do to make the boat move in the direction that was intended.
And you don’t need to throw him over board, but he has to get off the boat.
If you’ve stated your case and he’s bent on sabotaging the travels of everyone on the boat, there is no other logical choice.
Surrounding yourself with people on a similar trajectory is mandatory. If you can’t find anyone on a similar trajectory, you’ll have to go alone. You won’t be a lone forever.
Namaste, my friends.
