For those who don't know what legos are: They are building blocks which have lots of different bumps, so you can connect different colored blocks in many different places and at different (usually geometric) angles.

That's what we mean here: that you can take a step, interrupt it in many places and stick another step on.

One thing that people try to do, a little too early, usually, is that they try to improvise. And that's ok. Just realize that, for the first 6 months or year, things won't work out 2 times out of 3. So, for those dances where you really want things to work, it's probably best to stick to what you know and just put them together in random orders.
