There is a difference in lifespan and health span. Ideally, we seek to optimize both, squeezing all we can into and out of our lives, while remaining healthy for the whole journey.
As leaders, we are directly responsible for the health and wellbeing of the organization - for the organization as a whole and for the members as individuals.
Organizations have life spans (just like humans). And they have health spans (just like humans).
If we are not educating ourselves AND our members about how best to optimize both the lifespan and the health span of our organization, then it's a pretty sure bet that those spans WILL NOT be optimized.
Leadership always means more learning...
