This is 100% true. My connections, education, references, knowledge, etc, all played into me getting this new job. It isn't like someone right off the street can walk in and do what I do. It takes years of experience and honestly, when you have these skills, you aren't out of work and if you are, it isn't for long. I know people in the IT World here in Atlanta that have up and just quit their jobs without having another lined up. They were able to find comparable jobs in a relatively short time. Why? 'Cause they are good, they know people, they have the experience and knowledge, etc.
When you are good, you aren't out of work for long.
