Great lesson from 300 movie : Train your employees and foster a culture that promotes loyalty.

The Spartans had a grim but effective process for making sure their society only contained healthy children. (If you don't already know what that process was, you probably don't want to). To put it mildly, their organization only accepted the best and brightest employees, who were trained and molded into effective killing machines. It sounds gruesome, but it's handy when your business involves protecting your community from a foe that aims to crush you.
Arguably, loyalty may be the most important aspect of a successful team. At one point in the battle, Leonidas and Xerxes meet up. The Persian ruler tries to reason with his foe, asking how Leonidas can possibly defeat him when "I would kill any of my men for victory."

"I would die for any of mine," replies Leonidas, suggesting that an employee who knows he's valued is going to fight harder for the company's survival than a miserable grunt in the firm. The king has a point. His 300 men are effective at killing what must be thousands of soldiers in the first few hours of the battle. And it's not that surprising. Xerxes literally walks all over his employees; but in Leonidas' enterprise, his staff takes ownership and pride in the company and has a stake in the firm.
