Woodrow Wilson is reported to have told a Princeton colleague, shortly after the 1912 election, "It would be an irony of fate if my administration had to deal chiefly with foreign problems, for all my preparation has been in domestic matters."

Wal-Mart, with its legendary focus on customer value in terms of price, is innovating in sustainability. Now, we're beginning to see the mirror image, a convergence, as the not-for-profit sector is beginning to serve more effectively by applying private sector accountability and efficiencies to social needs.

Bill Gates and Warren Buffett are among the most conspicuous advocates and representatives of this transformation.

Theodore Roosevelt regarded leadership as his one gift, the area in which he might be considered to possess genius. He presented his views on leadership throughout his voluminous writings.
