More than half of people who leave their jobs do so because of their relationship with their boss. Smart companies make certain their managers know how to balance being professional with being human. These are the bosses who celebrate an employee's success, empathize with those going through hard times, and challenge people, even when it hurts.

The best way to find a balance between doing your best and showing that you're ready for more is by developing other people. As tempting as it is to hoard knowledge, don't. Instead, make certain that there are others who know how to do important aspects of your job.

Emotional intelligence is your ability to recognize and understand emotions in yourself and others, and your ability to use this awareness to manage your behavior and relationships.

My childhood was bittersweet in many ways. We moved around a lot. By the time I was 10, I had travelled thousands of miles, often on my own. My parents were like my friends, so it felt like I didn't really have parents at all. But in a crazy way that was very liberating. It forced me to be independent, maybe a leader, and certainly a survivor.

I vividly remember a conversation I had many years ago in 1974, which marked a turning point in my leadership journey. I was sitting at a Holiday Inn with my friend, Kurt Campmeyer, when he asked me if I had a personal growth plan. I didn't. In fact, I didn't even know you were supposed to have one.

If you're dealing with a powerful leader, you're inevitably going to have a dialogue with her political past. It was always my intention to interrogate Thatcher's political life.

It's fascinating, isn't it, that whereas so many of our statues have been of military leaders, now it may well be sports stars who are the ones more likely to be so honored.
