Degrees or working long hours unnecessary to be a CEO or president

What's the secret to training someone to become chief executive of a large company or president of a country? Do they have to be inclined to work around the clock? Is it necessary to have a degree from a top flight university such as one of the Ivy League institutions in the US?

The short answer is "No", according to a nine-year study by Michael Lindsay, a noted sociologist and president of Gordon College, a Christian college north of Boston.
