I was playing tennis today with my best friend and regular opponent, who asked after a while, “What’s wrong with you? It seems like on every other point, you’re turning your head away from the ball to look at something else, right before you start your swing.”

Granted, we were playing in a big park with lots of interesting to things to look at all around. But he was still right. My eyes went wandering when they still had a job to do.

What was happening? There are various explanations, but here’s an attention deficit disorder model: my mind had played through the point faster than the point was done in real life. And while real life was still happening, my mind was no longer paying attention.

But regardless of the model — the sports and business worlds are full of sayings like, “follow through”, “stay until the job is done” or “don’t snatch defeat from the jaws of victory.”

These sayings make sense for many reasons: when we don’t budget our time, energy, or money well, it’s easy to run out of the essential ingredient before the goal is reached. Attention is yet another ingredient.

If my attention is wandering, there is somewhere it wants to go, so obviously it does not want to be where I am holding it in the name of some self-styled obligation.

Prather isn’t writing about ADD, but it’s nice to remember that sometimes a wandering attention is just fine.
