"Those things which hurt instruct." Benjamin Franklin
As true today as when said in the 1700s.
Pain is inevitable. What we do with it is a choice. 300 hundred years later billionaire hedge fund manager Ray Dalio said something similar...
"Pain plus reflection equals progress." The problem in our manic always-on lives is we rarely make time for the middle bit, i.e. reflection. Leaders in companies are particularly bad at this.
We say yes to so many things that there is hardly enough time to get everything done.
We rarely make time to celebrate completion. And almost never stop and reflect on how we went and what can we learn. In the absence of doing so it is harder to replicate success.
But of greater concern is that we don't learn from failure.
As Churchill said "never waste a good crisis."
