The benchmark of success is shifting in the first world. It's moved from financial security to working with your passion/purpose/calling. I reckon this has been redefined on the back of the economic crisis. If you can't afford to buy your own home at 35, have a nice car, annual holidays etc., then why work so hard in something you don't enjoy? Why not do something you enjoy? Why not re-design your life?
The fundamental problem is that your passion/purpose is not OUT THERE. You aren't going to find it by looking externally, but this is the first thing that everyone does.
