Brownian motion at work

My friend Jeremy gave me a riff about Brownian motion - Wikipedia, the free encyclopedia.

Brownian motion describes the random motion of a particle in liquid. Why random? Because a particle hits something and bounces off in a new direction. Do this often enough and it's basically impossible to predict what will happen next.

Brownian motion only occurs with particles that aren't very goal motivated. You probably know people like this. They start doing one thing, hit an obstacle and suddenly flop into a totally new direction.

Are your co-workers Brownian? How about your projects?
