The best leaders rarely talk how things ought to be done, their actions speak for themselves. Think of someone you admired and how many of the lessons came indirectly from the choices that they’ve made and the example they have set. Similarly, we need to be focused on how we are actually living and what choices we are making. That’s where our time and energy will be best spent.
As Epictetus put it,
“Never call yourself a philosopher, nor talk a great deal among the unlearned about theorems, but act conformably to them. Thus, at an entertainment, don’t talk how persons ought to eat, but eat as you ought.”
