When warm air moves over cool surfaces, fog can form. It’s happening here, on my property, as the considerable remainder of the snow is under 50° temperatures.
In the fog, smart people turn on lights, they drive more slowly, the change their plans, they get assistance, or they’ll even simply stop for a while.
Many people, in a career fog, simple keep going, recklessly, until they crash, often hurting others.
The philosopher Santayana said that the definition of a fanatic is someone who loses sight of his goal and consequently redoubles his efforts.
Don’t become lost or injured in your own fog.
