The ramifications of all this are undeniable. Leaders who can identify, hire, and cultivate employees who are humble, hungry, and smart will have a serious advantage over those who cannot. They'll be able to build stronger teams much more quickly and with much less difficulty, and they'll significantly reduce the painful and tangible costs associated with politics, turnover, and morale problems. And employees who can embody these virtues will make themselves more valuable and marketable to any organization that values teamwork.
