Swing dance, especially the original forms of East Coast and Lindy Hop, is all about fluidity and communication between partners. Movements are relaxed and springy, and it's all about sharing energy and fun. Check out someone like Peter Strom on YouTube, you'll see what I mean.
I've been dancing for a couple of years, and teaching for a few months now... there's always something new to learn and stuff to hone in my technique, but I had a great time even on the first day.
Remember that it's not all about throwing people around and doing aerials, I haven't even lifted my partner off the ground on the social dance floor... it's about style, improvisation, and getting everyone in on the fun!
