"Successful leaders are like icebergs. When you look at an iceberg, you see only about 10 percent of it, and the rest of it is hidden under the water. When you look at successful leaders, you see only a fraction of their lives. You see the part that looks really good, but there's usually a lot that remains hidden that's neither exciting nor glamorous. Tennis star Arthur Ashe said, "True heroism is remarkably sober, very undramatic. It is not the urge to surpass all others at whatever cost, but the urge to serve others at whatever the cost." True leadership is the same."
