As the 50th reunion of Harvard Business School’s Class of 1963 approached, we asked the class members if they had any advice to pass along to younger generations.

The world these 1963 graduates entered was also starkly different in terms of technology and culture. The members of the Class of 1963 lived most of their lives without the Internet, the eurozone, climate change, and a society with an enlightened of view of racial and marital equality. Could these people possibly have a relevant thought to share with those in their twenties, thirties, or forties? It is, in fact, because these Harvard grads have lived through all these massive changes that their perspectives count for so much. They have been a part of both the “before” and the “after” pictures of a world transformed.
