I recently had the pleasure of reading Essentialism by Greg McKeown. Actually the full title with subtitle is Essentialism: The Disciplined Pursuit of Less.
McKeown’s premise is that we can’t do it all, and the idea that we can is simply false and leads us down the rabbit hole in a maze of diversionary paths that keep us from doing anything well.
By saying yes to everyone, taking on everything, trying to please all parties, and kidding ourselves that we can always add just one more thing, we end up not doing those things that are most important to us. Instead we diffuse our energy, our will power, and even our interest.
