Chronic stress has a negative impact on performance as well as physical well-being. Sled dog owners, for example, must pause their dogs when running races before they tire to maintain top performance throughout the race; dogs will not pause on their own.
Farmers must allow the soil to pause and rebuild its nutrients to maintain high yields over the long term. Humans, too, must pause to rest and recover. Yet many people believe that they constantly need to fight, to not give in, but this approach creates diminishing returns.
You lose motivation, suffer from fatigue and withdraw from your circle of support. You no longer enjoy your passions, your activities, your accomplishments; these activities shift in your mind from aspirations to obligations.
