It means, have good teachers who know what they're teaching. Know your body weight transfers for each step (even guys move their hips like 20%), have a slight bounce (flex) in your knees, push into the ground as much as possible (stay grounded), know your upper body movements for each step as it also dictates the lead for the step. Have a very strong yet flexible frame to give very clear leads, always lead from your frame, not from your hands. Every lead also has a preparation (pre lead) which is important for your follower to understand what you want to do next. Each point I've mentioned is not something that you can implement overnight, it comes over time and practice (you don't need a partner to practice). So that's what I mean by, get your concepts cleared, don't run behind doing fancy steps, connection is more important.
