Two people carrying a couch is easier than one, and harder to steer. Teamwork trades weight for communication.

Help changes the shape of the problem rather than just reducing it. Two people lifting a couch share the weight and immediately need something they did not need alone, which is agreement about which way to turn. Group projects, shared rooms and teams all run into this. The load gets lighter and the coordination gets harder, and people who have only ever worked alone are often surprised that the trade exists at all.

When you ask for help this week, spend the first minute on direction rather than lifting. Say what finished looks like before anybody picks anything up.
