Stressed or Blessed
You can't "stress" your way to your goals. You can't "flog" your way to greater creativity, or leadership or focus. You can allow challenges to enlarge you.
A state of being perpetually busy and having "insufficient time" as a default setting is an addiction, or a confession of incompetence. The most amazing things are achieved in the world through leverage, through collaboration, through sifting the essential from the incidental. And no one has any more time than anyone else.
