Summary

We’ve been told that “oversharing” (TMI) is a social sin. But our guest today, Leslie John, who teaches at Harvard Business School, argues that TLI (Too Little Information) is far more dangerous. In her new book, Revealing: The Underrated Power of Oversharing, she shows how personal, vulnerable, even uncomfortable disclosures are the wellspring of trust, friendship, romance, and professional success.

and I was so focused on the wind that I neglected to move my own head. I have never done this

before. And when you hit 58, you start reading into things.

Is this normal clumsiness?

0:24.3

Is it an early flicker of dementia?

0:27.0

Or alternative explanation, maybe this story is a humble brag about my competitive intensity.

0:33.4

I don't think that's what it is.

0:35.1

I think I'm sharing this with you as an offering. An offering

0:39.1

of my imperfections, my clumsiness, and the emerging realization that I'm a little bit afraid of

getting older. In my mind, I'm still 28, but I occasionally see my future 70-year-old self in

the mirror, and it haunts me a little bit.

Have you ever had such fears? If you and I were talking together right now, here is where you

might share a story about your clumsiness, or maybe your aging fears if you have them. And this,

this might be the beginning of a friendship.

What I love about this is that it turns each of our embarrassments and misfires and setbacks, I have quite a few, into opportunities for connection. We've been told that oversharing,

1:35.7

or TMI, is a social sin, but Leslie argues that TLI, too little information, is far more dangerous.

She likens human connection to building a
