Advances in thinking, in products, in services come when people forget their perceptions and challenge the status quo. A story to illustrate
In ancient philosophy whoever could untie the Golden Knot was destined to become King of Asia. All who tried failed. Alexander the Great after trying decided to write his own rules, pulled out his sword and sliced the know in half...job done!
Often at work and in life we are blinded by what we see as constraints, our assumptions, our preconceptions.....if you are stuck, then challenge the rules, the status quo...challenge what you believe are stopping you from advancing...try a different approach.
