It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change, that lives within the means available and works cooperatively against common threats.

The most important factor in survival is neither intelligence nor strength but adaptability.

The world will not be inherited by the strongest, it will be inherited by those most able to change.

Species that struggle to adapt to survive will become extinct.

In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed.

One of the things that can keep you from going away is an openness to change. That's the point.
