Through my networking, I have found previous bosses, managers and coworkers (even those who had left the company that I last worked for). Quite a few of these people have started their own design house consulting companies. One of the owners of these new companies found me though one of my LinkedIn connections. We have met several times and are now collaborating on creating a computer program. While this is not bringing in income yet, it could possibly turn out to bring in quite a bit of income for the both of us.
So, make a list of past bosses, managers and coworkers find them and see what they are doing now. You never know when you will find someone who knows of a job opening that is now publically posted or finding someone to collaborate with on a new idea. Even if this collaboration does not turn out to create income; it keeps you busy, uses your job skills and keeps them current, can keep you sane in a lengthy unemployment period and it keeps your name out there.
Like the quote that I am sure everyone has heard at least one time "it is the squeaky wheel that gets the grease" the more that you are out there and in peoples minds the more likely you are eventually going to find a job. I think this is more true in these times than ever. I was looking in this Sunday's Dallas Morning News papers job section and there was only one page of want ads. Years back, the same paper had sections of want ads. Today's job market is not what it once was.
