Great leaders learn to combine their unwavering confidence with equally solid humility and selflessness. They know they are good but they don’t make an issue of it. They know they are not perfect but they don’t freak out about it. They know they know a lot, yet they are eager to learn from others. When things go wrong, they accept responsibility and are ready to show vulnerability. When things go well, they make sure the team is credited.

I was stubborn. Now I am persistent. I was self-centric and self-serving. Now I value equality and mutual respect. I was a day dreamer. Now I can envision things and think creatively about strategy. CEOs are not born; they are made – by themselves and by people around them.

Focus is not what you do, but what you choose not to do. Startup CEO Kristo Ovaska learned the hard way to say “No”. He now declines long meetings, non-vital emails, external press requests, speaking engagements, and investor contacts that are not yet needed. This has brought about an entirely new level of productiveness.

Culture and values are a top responsibility for CEOs of both start-up companies and large corporations. A company with a strong and consistent culture requires less command-and-control management and empowers employees to take initiative, innovate, and serve customers well, says Fadi Ghandour.
