What physicists REALLY do.. or just why

Well, truthfully, Preposterous Universe didn't really explain to me what a physicist does on a daily bases. However, it does seem to me that in order to do physics for your entire life, it's extremely important that you love it. Even though my guy doesn't talk about his own work on his blog, he's always going on about some new development in the world of physics and seems to be genuinely excited about it. It's possible this is just a special case, but I hardly think so. I think it helped me so how important it is to really love what you're doing in order to be happy doing it. I guess it's the same with most jobs, but in physics, as well as most other sciences, it's important to be extremely dedicated because the research projects can last so long.
