My work is not exactly Nobel Prize-worthy, but it is interesting and hopefully useful in the medium term. And since I'm not ready to publish it yet, that means I can't give an oral presentation on it, just a poster and a flash talk.
But of course this is good enough to give it my best shot, so this week I am in full presentation mode. Getting all the materials ready, printing out guides, modifying my poster, and endlessly practicing what I am going to say to fill my allotted time with useful things about my work without unnecessary details. 
One point of difficulty is that most people will be presenting (and interested in) a quite different area of research, so I really need to present my work from a very basic perspective in order to be clear. Nevertheless, most of my old work was in that different field, so at least I have the experience of knowing what kind of things (from vocabulary to techniques) are new to the audience, so I hope I will be able to adapt my talk to them.
It is also a lot of fun because I am really interested in what everyone else is presenting, even if it is not even remotely related to my current work, it is a little bit like going back a few years and going to these kinds of scientific meetings all the time.
