As a career coach, I spend a lot of time talking to job seekers about improving their resume, how to answer interview questions, how to find jobs by contacting hiring managers, etc.--but very often the biggest issue in the way of their success is a simple lack of confidence. They're full of fear that keeps them from doing what they need to do to get a job.
"What would someone who didn't care what others thought, or didn't care if the answer was no, do?"
Think about that for a second...got your answer? Great. Do that.
