Zen isn't only about being in the now. 

It also involves being mindful about the future.

In experiential education, we are mandated to come up with contingency plans.

This was in mind when I stopped in Pemex, a Mexican gas station.  

Posted in on the wall was the contingency plan.

The first step, "Maintain the calm, in order to think better." 

continues to captivate me as one of the best pieces of sign-based advice I have ever received.
