At some point, the world (the project, the moment) becomes so chaotic or dangerous that we sacrifice law in exchange for order.
The question is: when.
When is it time to declare martial law? (or your version of it)
When do you abandon your project plan because the boss is hysterical? When do you go off the long-term, drip-by-drip approach to growth because cash flow is tight? When do you suspend one set of valued principles in order to preserve the thing you set out to build in the first place?
When Richard Nixon was at his most megalomaniacal, he was willing to suspend any law in his way to preserve what he saw as order. Failed entrepreneurs and project leaders fall into the same trap: it feels as though this time, it truly is the end of the road, and throwing away principles is tempting indeed.
You've probably met people who declare this sort of emergency ten times a year.
History is filled with examples of people who pushed the order button too soon… but few instances where people stuck with their principles for too long.
