Where's the Lebensfreude?

This is something that I am missing here. Not only from myself, but from others as well. Lebensfreude is something like lust for life, or zest for life or pleasure of life. It just doesn't seem like many people around here are radiating this, sie strahlen keine Lebensfreude aus, as you would say in German. What's wrong here? Why do the people I know here who have jobs they like and spouses they love and everything they need not have this? I was just looking at some pictures from Germany, and in most pictures, I was reminded of people who were just radiating this sort of satisfaction there. Even if they weren't rich or necessarily in the greatest relationship or whatever. Then I wondered "And here? Who do I know here who shows this kind of excitement for life?" And I can't think of one. Maybe one of the teachers I had a coffee with this afternoon, but she's the only one who pops into my head right off the bat. Why? What's wrong? Obama, can you help us get our excitement for life back? That's the change I need. But I think I'll need to take care of this one myself, I don't think any president can fix this problem.
