We're all busy. Chronically so. As Henry David Thoreau said,
"It's not enough to be busy. So are the ants. The question is: What are we busy about?"
One thing is certain, if you want to be less busy, hiring a manager to report to you is not always the answer. Even a Junior Manager brings extra overhead.
Sometimes, you'd be better off, for example by,
"creating standard processes for handling queries and ideas from front-line people, that will help them make and execute good decisions faster."
Just one of the excellent insights from one of Michael Mankins' early works.
