if someone under you does something spectacular, that just shows the company that you’ve built a great team. And that you should be rewarded for it. There should always be at least one or two people on your team who are natural successors to you. Those are the people you have more 1:1s with, who you pull into leadership meetings, who everyone will begin to notice. The more they notice them, the better. That will make it much easier for you to get promoted, because there will be no question about who can run your team when you move into another role.
