Where deep practice is a cool, conscious act, ignition is a hot, mysterious burst, an awakening. Where deep practice is an incremental wrapping, ignition works through lightning flashes of image and emotion, evolution-built neural programs that tap into the mind's vast reserves of energy and attention. Where deep practice is all about staggering-baby steps, ignition is about the set of signals and subconscious forces that create our identity; the moments that lead us to say that is who I want to be.
