Admiral William McRaven, an amazing military leader, a retired Admiral and former US Navy SEAL. He served as the ninth commander of the US Special Operations Command. He was also Chancellor of the University of Texas System.
Recently he came to the attention among people who’d never heard of him when the Commencement speech he gave at the University of Texas at Austin, entitled “Make your bed”,went viral. Here’s a link to that speech.
He was asked recently which national security threat keeps him up nights, and he explained that it’s K-12 education. He makes great points.
