Taking Initiative: asking good questions of others and yourself

One of my favorite bloggers on work issues, Steve Roseler, had this recent post on helping good people grow by asking good, probing questions. These questions are good to ask a manager when you're assigned a project, as they help you understand what the manager needs from you. But the questions are good to ask yourself when you're trying to solve a problem, especially when there's no one around to help you.

Have you ever had a manager ask you a good question or frame a problem in such a way that really changed the way you think about your job and/or your work?
