Book excerpt: You are not perfect. Never have been, never will be. And no matter how much experience you gain, how long you contemplate a decision, or who you seek counsel from, you will still make the occasional management misstep--a few of them. Guaranteed. And if you stay in management long enough, you will undoubtedly ask yourself questions such as:• Why do I sometimes feel threatened by my best people? • How do I remain cool in hot situations? • How can I ensure people hear what I say? • How can I cope more effectively with change? • Why have I lost so many of my best employees to the competition?The question is, will you wait for these mistakes to happen and then stay awake at night dwelling on these questions, or will you address them proactively so that you may discover the right solutions to apply now? Clinical and business psychologist Nicole Lipkin knows the stresses leaders face. In What Keeps Leaders Up at Night, she examines the common mistakes leaders make with their people. Featuring illuminating examples and exercises, this sleep-friendly book shines a bright light into the dark corners where all leaders struggle with their own shortcomings and presents smart solutions to the problems that arise as a result.
