Perhaps you can't see it, but we can. That 2 x 4, the board set right across that doorway, about 5 feet off the ground.
You're running it at it full speed, and in a moment, you're going to slam into it, which is going to hurt, a lot.
This happens to most of us, metaphorically anyway, at one time or another. But when it happens repeatedly, you probably have a hygiene problem.
Emotional hygiene, personal hygiene, moral hygiene, organizational hygiene–useful terms for the act of deliberately making hard decisions, early and often, to prevent a 2 x 4 to the face later.
Worth a pause to highlight that: hygiene never pays off in the short run. It is always the work of a mature person (or an organization) who cares enough about the later to do something important in the now.
When the doctor scrubs with soap before a procedure, it's not because it's fun. It's because she's investing a few minutes now to prevent sepsis later.
Way better than getting hit in the face with a 2 x 4.
