The ability to be alone is the ability to love. It may look paradoxical to you, but it's not. It is an existential truth: only those who can be alone are able to love, to share, to go into the deepest core of another human being—without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other.
Sustainability is no longer an option; it's a necessity for any business that wants to thrive in the 21st century.
The only way to do great work is to love what you do.
