Interesting question. I also read through the HBR blog by W.J. Your disruptive skill is not easy to identify unless you also have the ability to expand your Johari window. Unless you minimize your unknown-unknown window, you don’t have the opportunity to realize the disruptive skills. What you do daily isn’t your disruptive skill. It is those unique skills that help you redefine yourself and also makes others see you differently. Disruption can happen only when you have realized it and for that, you need to be aware of the skill.
