There’s another reason promotion to manager—or to a more senior level of management—is tough. It’s because change of any kind is difficult. Even so-called positive change. Presumably we are supposed to be happy about “good” change. So we feel guilty, on top of everything else, for having a negative reaction to positive change.
Change, by definition, means a departure from the status quo. Positive change—a promotion, a partnership, a bigger sales territory, a new home—still signifies a loss, letting go of the familiar. What we know and are comfortable with is gone. A wise entrepreneur I know describes times of successful transition as “being positively challenged.”
So cut yourself some slack. Part of the reason you miss your “real” (aka previous) job is because it was what you knew. Now you’re playing by new rules, with new expectations and new demands. Easier on paper than in practice. It’s okay, though. Believe it or not, you’ll get the hang of it.
