Closure — that's actually a very good way to put it. I didn't feel burned out. Just tired and complete.
But I was very fortunate to have the means to retire. Many who experience burnout don't have that choice. Which is another reason there's such churn in this business.
As a manager, one thing I always watched for were the signs of burnout. I always said I spent way more time coaching people to pace themselves than to work harder.
