From Try to Take My Position: The Best Promotion Advice I Ever Got - AGY
If you want to be promoted, you need to demonstrate that you can already handle the role you’re trying to grow into. Not occasionally. Consistently. The title follows the behavior, not the other way around.
So if you want to get promoted: try to take your manager’s position. Start thinking about the problems they think about. Make the proposals they would make. Expand your vision to the team’s problems, not just your individual tasks.
Do it for six months, not six days.
