Leadership is a quality rather than a job. We are all leaders and followers at different points in our lives. Many aspects of this book should be useful to those looking to grow as leaders as well as managers, and great managers should cultivate leadership not just in themselves but also within their teams.

This is an important distinction because while the role of a manager can be given to someone (or taken away), leadership is not something that can be bestowed. It must be earned. People must want to follow you.

New managers sometimes ask me, “A decade into the job, what’s something you’re still continuing to learn?” My answer is, “How to be the best leader I can while staying true to who I am.”

Managers so often think of the role as being in service to something else—the mission of the organization, the goals of the team, the needs of others—that it’s easy to forget about the most important character in your management journey: you.

Design a job as though there’s no love in it, and it’s a self-fulfilling prophecy—you wind up designing loveless jobs in which the best have to actually break the rules and regulations in order to find love in what they do. As far as we can, it’s up to us to try to persuade our leaders that this is wrong. That if we can define jobs through the lens of those who love them then higher performance, higher quality, and less burnout are the happy result.

No, you won’t ever find the perfect job, a job you love 100 percent of the time. You won’t ever “do only what you love.” But you can —every single day—find some activity or situation or moment or event that you love. It might be the thinnest of red threads, but you can find it.

Let’s face it, no one, regardless of how experienced or talented, is equally adept at every aspect of a job. In any case, as Immelt points out, even if you are above average across the board, no leader has the time to concentrate on every aspect of the job, especially in the earliest days of a new position. Think about where your personal involvement will yield the most leverage and where someone else might do an even better job.
