What was the easiest, earliest, thing you could do in a Lucid Dream?

For me it was manipulating clouds, I even do it when I'm not thinking about it. My first LD I looked up at the sky and moved clouds around and changed the sky's color. My last LD I was trying to fly by laying down and moving the objects in my perifery rather than trying to move myself and I started to form and move clouds. Maybe it has something to do with clouds being rather 2-Dimentional and distant rather than solid, immediate objects that makes them so easy to manipulate.
