.... there are always multiple paths to the same end (equifinality), and the same starting point can be a path to many different ends (multifinality). We should be careful to avoid getting too attached to a particular route or even a particular destination.

This quote from Part 4, Chapter 11 illustrates Grant’s point that there isn’t just one definition of success or one track to happiness. According to Grant, careers, relationships, and communities are examples of what scientists call “open systems,” those that constantly change because they are not closed off from their surrounding environments. Grant urges people to accept flux as a positive state of being. The willingness to rethink life plans can lead to personal growth. Although American culture tends to admire the grit shown by those who stick to their original choices, Grant encourages readers to remain constantly flexible and open to change.
