Weather can alter the day without defining the climate.

A terrible week of rain says nothing about whether a region is dry. We consistently confuse the two, treating a bad day as evidence about our life and a good one as proof that everything is fixed. The signal is in the average, not in today.

When a day goes badly, try describing it as weather rather than as a verdict. If the same weather persists for months, that is climate and worth acting on. The distinction saves an enormous amount of unnecessary despair.
