IMHO, the key to reliably producing quality results means combining “speed of perception” with consistent audacity. The faster you perceive what fits in your story, and the more audacious you are in instantiating it, the higher the pay-off for your audience, and the faster you can cycle on to a better project, which in turn causes your skills to grow with increasing rapidity. Others will look at you and dismiss you as lucky or talented, but in reality, nothing could be further from the truth.
At this point, I believe you have simply honed your perception and audacity to such a degree that it can convincingly masquerade as luck or talent.
