EXCERPT: The Moment That Changed Arianna Huffington's Life

ARIANNA: I actually collapsed from exhaustion on April 6, 2007, two years after I had founded the Huffington Post. I hit my head on my desk, broke my cheek bone, got four stitches on my right eye. I was very lucky I didn't lose my eye.

OPRAH: Didn't you sort of -- you went unconscious and then woke up and you were in your own pool of blood?

ARIANNA: My own pool of blood, yes.

OPRAH: Yeah.

ARIANNA: And then in a way what is worse is I had to go from doctor to doctor, from MRI to echocardiogram to find out what was wrong with me, you know. Did I have a brain tumor? They didn't know what was wrong.

OPRAH: Mm-hmm.

ARIANNA: And they discovered there was nothing medically wrong with me, but just about everything wrong with the way I was leading my life and what I was prioritizing. And waiting -- you know, doctors' waiting rooms are great places to ask life's big questions.

OPRAH: Whoa, you had some time there.

ARIANNA: It was Super Soul Sunday questions.

OPRAH: Yeah. Yes. The big questions, yes.

ARIANNA: So I was asking myself. Is this success? You know. By conventional definitions of success, I was successful.

OPRAH: Right.

ARIANNA: By any sane definition of success, if you are lying in your own pool of blood on your office floor, you're not successful.

OPRAH: Because you were so exhausted.

ARIANNA: Because you're so exhausted that you collapsed.

EXCERPT: How to Know When It's Time to Shut Off the Smartphone

ARIANNA: The other thing that people do, which I stopped doing after my fall, was to sleep with a smartphone next to their bed.

OPRAH: I know. You told me that you not only don't sleep with it next to your bed. You, Arianna Huffington, have a time where you shut off all the devices.


OPRAH: And you remove it from your bedroom.
