Line or staff?
The most urgent jobs tend to be line jobs. Profit and loss. Schedules to be drawn and honored. Projects to deliver.
The line manager initiates. The line manager delivers.
Staff jobs are important, no doubt about it. The staff keeps the lights on, provides resources on demand and is standing by ready to help the line manager. But the staff person doesn't get to say yes and doesn't get to say go.
In fact, the best staff people get that way by acting like they're on the line.
When you can, take responsibility. Say go.
