You have an impressive resume and tons of experience -- why aren't you being sought at work for your expertise? The answer is initiative. Initiative takers are seen as leaders, and your resume is secondary to how you are perceived by your actions in the workplace. Initiative takers naturally expand their own influence and value by being willing to take on new things. When they do this appropriately, without elbowing or appearing overzealous, managers and peers seek them for their opinions and solutions. Speed your ascent to becoming the perceived "resident expert" by taking more initiative.
