If you could have a conversation with your younger self, what would you tell them?

Anonymity is our most valuable gift.

I'm Kristi Young, and in Young again, I'll be asking my guests what honest advice they would give their past self.

Believe it when they say that loving yourself is the answer.

Among those joining me will be Jamie Oliver, Jeda Pinkett Smith and Mel B.
