A lot of jobs that once were, aren't coming back. Ever. To look for what isn't there is a waste of time and an insult to your dignity.
If you haven't noticed, the world has changed -- radically. The traditional yellow brick road to success and financial security has imploded. The path to a high-paying job used to involve getting the highest academic degree you could obtain, along with specific technical job skills, to start climbing the ladder. Today, most of the ladders are decimated. If those jobs still exist, the needed knowledge and skills of those jobs have changed... and change again every day. These are the greatest times of opportunity we have seen in human history -- but only if you know how to seize them.
