"Be comfortable with vulnerability" We're continuing our season "Mission-Driven CEOs". Top Chief Execs talk about the impact they want to make beyond just the financials - in terms of the company mission and their personal leadership legacy - and how they put that into practice on a daily basis.  Today Joshua Lachs speaks with Richard Medcalf. Joshua is CEO of Moneythink, a not-for-profit organisation on a mission to help students understand their financial options and the impact of their choices so they can have the best chance for college and career success.
