For most of us, lucid dreaming involves a number of factors coming together. You have to want to lucid dream. You need enough sleep and not be too tired. You have to try to recall your dreams, waking up after a dream so you recall it. And journalling which has a number of benefits. I usually need a short WBTB. Now, RC'S I don't need to practise quite as much, but these other factors still come into play. That's not to say you can't LD without these, but your frequency will probably be much less. It's not like riding a bike, but more like being a professional golfer...you won't stay there without the discipline.
