“The good life is a process, not a state of being. It is a direction not a destination. “
After a quick search (note: not ‘research’), I found that it was actually a quote from On Becoming a Person (1961) by Carl R. Rogers, who is one of the preeminent psychologists of the 20th-century. Rogers is best known for creating what is known as client-centered therapy, a nondirective approach that places the client in control of the therapeutic process.
Another insighful quote from the same book is:
“A second characteristic of the process which for me is the good life, is that it involves an increasingly tendency to live fully in each moment. I believe it would be evident that for the person who was fully open to his new experience, completely without defensiveness, each moment would be new.”
