Joe Deitch is a man of many talents. Known first and foremost for his role as founder of the Commonwealth Financial Network — the largest privately-held independent broker-dealer — Deitch is also a developer of premier golf courses, a Broadway producer (and Tony Award winner at that) and now a self-help author, with the release of “Elevate: An Essential Guide to Life” earlier this year.

But whom does he think is the most interesting person in the world? (Hint: it’s a man who works at Fidelity).

For Financial Planning’s Lightning Round, Deitch also fielded rapid-fire questions about the book-writing process, tips for building relationships with clients and his favorite way to consume information.
