You have a goal. Everyone is pointed at it. Everyone is rowing their butts off, together, to get there.
Someone keeps rethinking the destination. Goes on day excursions to other destinations.
They zig and zag when everyone is running in a straight line.
They keep throwing the shiny object up in the air.
That constant tug of misdirection can pull you into a circle, or if left unchecked could put you into a spiral circling the drain.
Everyone pulls together or someone gets put into another boat.
