You know what you're good at. You fill a certain niche at work, produce top-quality results, and are always on call when someone needs you. It's gotten you far and you like it. That said, your job performance has come to the attention of certain superiors who would like you to take on more. They see you as someone who could run things more smoothly and increase efficiency. The question is: do you? It's flattering to be held in such high regard, but think about the lifestyle changes and whether they're worth it. Nobody's ready to make the offer yet, but they will be soon.
