Most of us think of mentoring a colleague as a one-way street—a gift of professional guidance and advice. But Sylvia Ann Hewlett says sponsorship needs to be a reciprocal relationship.

“[T]he younger person has to display a great deal of value. And oftentimes the senior person is looking for a value add, a skill or an experience in the younger person that they don’t have themselves,” she explains. “So it’s very reciprocal…and it’s really about progression for both of the individuals.”

Hewlett is an economist, consultant, and the author the book The Sponsor Effect: How to Be a Better Leader by Investing in Others.
