When a ship enters the Gatun Locks of the Panama Canal, there's risk to both ship and lock. A few feet to port or starboard can make the difference between a safe passage and a dangerous collision with one of the lock walls. That's why the locks have guide walls, or fenders, that jut out from the lock entrance at about a 45-degree angle, roughly in the shape of a V.

These walls guide errant ships toward the lock, making sure that the ship is "in the groove." Scott Acone of the US Army Corps of Engineers explains that the structure "…ensures that the ships make it into the passage without a direct hit on the lock itself. They ensure a more glancing blow, which doesn't damage either the ship or the lock."
Our minds have "guide walls" too. When we've used a particular behavior frequently, we develop "grooves" that make it easy to find that behavior again without thinking. But there's a price — when we aren't thinking clearly, the only choices we can make are those that require no thinking. And the patterns we're most likely to find are those with the most effective guide walls.
Under stress,
we sometimes behave
like children. Why?Under stress, we tend to use behaviors that we learned long ago and that we've used a lot. And those behaviors tend not to be the ones we learned more recently, as mature, thinking adults. Instead, we find more easily the behaviors that we learned long ago, as children, when our choices were more limited. That's one reason why, under stress, we sometimes do behave like children.
Where do your guide walls take you? We're all unique. Some popular destinations are anger, helplessness, abusing others, wackiness, retreat, hero worship, medication, stuckness, and complexity. You probably know yours — maybe too well.
Here are some tips that can help you find the choices you'd like to make instead.
- Learn to notice stress
- Canal locks have much more protection than just guide walls. There are lights and buoys and other warnings that alert pilots to the approaches.
- Knowing that you're stressed is the first step to better choices. Learn what your own stress symptoms are, and practice noticing them.
- Slow down
- Canal pilots ease their ships into the locks very carefully. They need time to make course corrections.
- If you notice that you're stressed, slow down. Breathe. Give yourself time to make better choices.
- Accept the need for practice
- The guide walls at the Gatun Locks are massive, and took time and tremendous effort to build.
- Our guide walls aren't physical walls, but building them takes time, too. We build them by choosing consciously, and by observing our own progress.
Changing — building new guide walls — takes practice. That's why every stressful situation is a gift. It really is your only chance to practice. Top

Coming July 16: Responding to Unwelcome Events
- Unwelcome events have two kinds of effects on decision-makers. One set of effects appears as we respond to events that have actually occurred. Another set manifests itself as we prepare for unwelcome events that haven't yet occurred, but which might occur. Making a wrong decision in either case can be costly. Available here and by RSS on July 16.
And on July 23: Microdelegation
- Microdelegation is a style of delegation in which the delegator unintentionally communicates the task to the subordinate in such detail and so repetitively that the subordinate is offended. As a result of this delegation style, many subordinates feel distrusted or suspected of fraud or goldbricking. Available here and by RSS on July 23.
