There is almost nothing more painful for a leader than seeing good people leave a growing organization, whether it's a priest watching a Sunday school teacher walk out the door or a CEO saying goodbye to a co-founder.

Anybody, and any company, can have a big run of success once, but if you're going to repeat that over time, you need to be aware that you need to keep learning.

I have yet to meet members of a leadership team who I thought lacked the intelligence or the domain expertise required to be successful. I've met many, however, who failed to foster organizational health. Their companies were riddled with politics, various forms of dysfunction, and general confusion about their direction and mission.

The truth is that intelligence, knowledge, and domain expertise are vastly overrated as the driving forces behind competitive advantage and sustainable success.

Your success can't be determined by your surname but only by your work.

Mere longevity is a good thing for those who watch Life from the side lines. For those who play the game, an hour may be a year, a single day's work an achievement for eternity.

In the U.S., my whole life, I felt like I had to be the best and score more goals and run with more fitness so I could be the one in the limelight. I think that when I went to Sweden, I found the joy of being part of a team and contributing to everybody's success.

The most important thing to strive for in life is some kind of personal and professional achievement. Not as a man or a woman, but as a person.
