I joined my local chamber, found some networking groups, attended meetups and mixers, etc.
You will be amazed by how many people you meet that can help you with your business/job search either by providing a service that you need to further your career, or actually lead you to work - either directly or through referrals. Remember the 6 degrees of separation game? Well it is especially important in business. They always say: it's not what you know, but WHO you know. So, get out and meet people and get to know them!
