In salsa (and similar in BR latin), rhythm is the main thing; you absolutely need to get stepping on the beats into your muscle memory of legs and body. Find some salsa music and just step on the beats when you have time, cooking, brushing the teeth etc ... It's not just stepping, but moving the hips as well ... This is much more important than actual direction of particular step, I would actually suggest doing it on the spot first and later practicing it forward/backward/side with short steps first etc. In real social dancing, different partners will be leading similar moves different way, some of your steps will have to be shorter, some longer than you are used to, but as long you can step on the feet below you on the beat, you will be pretty much ok. It will also make easier to follow leaders dancing on1 or on2, if it's a mixed venue like mine - timing of the steps is the same (123-567), but direction of particular step is different, and when those directions come into your muscle memory before the rhythm, it's not that easy to do things just almost opposite way ...
