This is what I came to realize as well, and it's what frustrates me. I have one of simplest job in the world (I see other people in other fields working so hard, for much less money), and I can't manage it because I'm so bored and frustrated). And that feeds back to even more frustration and unhappyness. I'd hope that I can find some meaningful job. At least something that makes sense a bit.

There's a lot of truth in what you write. Thanks. Problem is, I am extremely goal oriented person. I need a carrot in front of me to chase - that's what drives me and what makes me get up at bed. I used to do sports professional when I was younger, and I was always obsessive about wining, up to putting tremendous hours into it. My self-analysis, maybe completely wrong, is that I carried it into my adult life, but can't find nothing meaningful to compete in now.
