Over two thousand years ago, a father chose the greatest scholar of his age to tutor his young son in liberal arts. The gifted instructor taught the boy architecture, music, literature, politics, and natural sciences. A few years later, the boy, barely in his twenties, set out to conquer the world. He did. By the age of thirty, he had created one of the largest empires known to man, stretching from the Ionian Sea to the Himalayas. He was undefeated in battle and remains one of history’s most successful commanders. Alexander the Great died at the age of thirty-two. Many of his contemporaries considered him a drunk and a womanizer.
