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.

One of the biggest mistakes new bosses make is thinking they need to jump in and exert their opinions right away to show that they are capable.

Actually, that approach tends to backfire. Few things are more annoying than a new person wasting everyone else’s time because they are trying to prove they know something when their opinion isn’t actually informed.

Your job as a manager isn’t to dole out advice or “save the day”—it’s to empower your report to find the answer herself. She has more context than you on the problems she’s dealing with, so she’s in the best position to uncover the solution. Let her lead the 1:1 while you listen and probe.

Hiring a manager or senior contributor onto your team is a big investment, and bad leadership hires are disproportionately more disruptive because they affect more people. If you bring on a new manager whose values aren’t aligned with yours, he will hire people that you may not think are a good fit. If he turns out to be a crummy collaborator, you’ll be dealing with a line of complaints out the door.

It’s wise not to rush into leadership hires, and instead make sure you know what an ideal applicant looks like. The easiest way to do that is to talk with as many prospective candidates as you can, including those who may not want the job but know the role well. Especially if you’re hiring for an unfamiliar position, you need to do your homework to understand what the bar should be.

There are two major errors with that line of thinking. The first is overestimating what you, the manager, are capable of. Yes, it may be within your power to solve a wide variety of issues, but as a single individual, you can’t solve that many of them. The best work comes from those who have the time to live and breathe a problem fully, who can dedicate themselves to finding the best solution.

The second error is assuming that nobody wants to take on hard problems. In fact, the most talented employees aren’t looking for special treatment or “easy” projects. They want to be challenged. There is no greater sign of trust than handing your report an intricately tangled knot that you believe she can pull apart, even if you’re not sure how.
