Your first three months as a new manager are a time of incredible transition. By the end of it, the day-to-day starts to feel familiar—you’re adapting to new routines, you’re investing in new relationships, and you may begin to have a sense of how you can best support your team. But time isn’t a substitute for comfort. That new-kid-at-school feeling may linger for months or years longer. New managers often ask me, “How long will it take to feel like I know what I’m doing?” I reply quite honestly, “It took me about three years.”
