A friend of mine, his coach reminded him of this simple though valuable saying on effectiveness.
Apply this to anything in life, and live up to the fact that it’s important enough to measure and thus manage.
But beware. Not everything is worth measuring.
For me personally, I’m working towards more financial effectiveness and thus in need of measures and of better measures.
I think effectiveness, synonym for impactful decision making and acting accordingly, is the root of all success in life.
