Emmitt Smith has run past legends, danced with stars and posed for the sculptor crafting his Hall of Fame bust. Hes built upon his athletic talents by working hard, seizing opportunities and reaching out to others for advice when he needed it.

We all think that the answer to everything is to add more and to do more and to try more. Sometimes you have to have the discipline to say no and to believe in the process that you have established.

Companies that understand the purpose and philosophy behind the "why" are usually astute, high- performing organizations that tap directly into the pulse of those they benefit the most. When utilized correctly, this understanding can create a powerful sense of duty and purpose for business teams because the employees know exactly whom they are working for and to what end.

The challenge CEOs will face three to five years from now is the same one that they face today. That is engagement. It's hard to keep people engaged in what they are doing. As this generation grows up around social media like Twitter where things are 140 characters, how do you keep them engaged all hours every day at work? How do you keep them focused on the big goals you have?

Sometimes legends find themselves remembered more for what they have not done than for their accomplishments. But those resume gaps can also help drive them to achieve even greater things in new arenas.

I'm a believer that charisma makes a huge difference in people's decisions to follow you. However, it's not just that you say it well, but it's that you know it well. It helps if you can say it well enough that people want to follow you. Charisma isn't required, but it makes a big difference.

Leadership belongs to all of us. I'm a big believer in John Maxwell, a leadership speaker and author, who talks about the 360-degree leader. Before leading others, you have to learn to lead yourself. Wherever you work in an organization you have to learn to lead up, lead down, and lead side to side. Leadership belongs to all of us. You have to see yourself, and believe in yourself in the way that we are talking about here to give to those that you lead.
