As a manager, you are judged on your team’s outcomes, so your job is to do whatever most helps them succeed. If your team is lacking key skills, then you need to spend your time training or hiring. If someone is creating problems for others, then you need to get him to stop. If people don’t know what they should be doing, then you need to construct a plan. A lot of this work is unglamorous. But because it’s important, it must be done, and if nobody else does it, then it falls to you.

This is why adaptability is a key trait of great managers. As your team changes—whether it’s goals shifting, people joining or leaving, or processes evolving—what you do every day will also change.

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.

When the sailing gets rocky, the manager is often the first person others turn to, so it’s common to feel an intense pressure to know what to do or say. When you don’t, you naturally think: Am I cut out for this job?

The second reason is that you are constantly put in the position of doing things you haven’t done before. For example, say you have to fire someone. How do you prepare yourself for such a task? It’s not like improving your skills in drawing or writing, where you can invest time on nights and weekends to sketch or compose short stories. You can’t just snap your fingers and say, “I’m going to practice firing a lot of people this month.” You must actually go through the real thing in order to gain the experience you need.

Management isn’t an innate skill. There is no such thing as an “all-around great manager” who can transition effortlessly between different leadership roles. We must look at the specific context.

Since every hire is already a gamble, reject any weak hires. While they’re not likely to bomb, they’re also not likely to add much. If you’re going to make a bet, bet on someone with a passionate advocate behind her. If a candidate gets mixed reviews but all the interviewers that said hire are adamant about wanting to work with her, it’s usually a sign that she brings something highly valued to the table.

The lesson: Recruiting top talent is all about the relationships you build. Good, seasoned leaders aren’t short of options, because everybody wants to hire them. When they’re looking for their next role, they tend to choose opportunities that they already know to be great.
