Before I found DV and read about the nose pinch RC I never even used standard RCs. I just became Lucid from questioning reality all the time.

Once during a stressful time in my life I went about my day pretending I was in a dream, and just kind of laughed at all the things that would have normally gotten to me. The intention was to reduce the stress, not to induce Lucidity. But to my surprise I ended up having a spontaneous Lucid that night. So I know it can work.

I'm not ready to give up on the RCing now though. Even though I often become Lucid without the need for an RC. There are still those times when I might question if I'm in a dream and then decide I'm not when I actually am. Those are the times when a simple RC check can really save a Lucid.
