The reason why we complain about the heat isn’t that we are uncomfortable, it’s because there is nothing we can do to change it.
We can’t ask the sun to turn down the temperature.
The thing is, we tend to complain about things that are out of our control. Because…
Our time, energy, attention are all finite resources. Because inconvenience and being uncomfortable brings tension that can’t be resolved.
The best answer I can give is to wear some sunscreen, find some shade and continue to do your work.
Your time isn’t being well spent complaining about things you can’t change. And with things you can, they need your attention.
