Thanks for your feedback! For myself I can say, that I also work all day (and sometimes even stress me about getting not enough things done). But as it's mostly self-determined work, it feels natural and right. When I worked for other people, I often felt heteronomous and used very often. So I guess, I should follow my instincts and make a living by doing what I want to do (however you call it).
When I bought the video camera, it somehow became obvious, that this could be the way to go regarding my jobwise direction. And so I became a Cameraman and Editor some years later. I guess, it didn't has to do with my camera work (and the great zooming), rather with the ability to catch a certain moment in time.
