The second book in Ryan Holiday's Stoicism in the 21st Century series, in which he examines the 4 virtues of ancient philosophy (courage, moderation, justice, wisdom). In his new book, Holiday celebrates the amazing power of self-discipline and those who master it. Holiday turns to historical figures we can emulate, including Lou Gehrig, Queen Elizabeth II, boxer Floyd Patterson, Marcus Aurelius and writer Toni Morrison, as well as cautionary tales of Napoleon, Francis Scott Fitzgerald and Babe Ruth. Through these fascinating examples, Holiday teaches readers the power of self-discipline and balance, and warns against the dangers of extravagance and hedonism.
