To find a job, you need to be ready to market yourself at any time. Make sure you're equipped with the right pitch - don't be afraid to toot your own horn, and don't waste time reiterating your resume. Instead, state in one concrete sentence what makes you so effective.
Talking about the impact you've had - and can continue to have is much more compelling than listing your experience.
For example, one assistant said of herself, "I can make any boss shine". Speak at a pace that shows you are calm and confident. Practice your pitch often. And remember that jobs don't just come from interviews.
Use any opportunity you have to deliver your pitch - at family gatherings in waiting rooms, or at the coffee shop. Don't wait for the elevator.
