Discontinuous improvement
Continuous improvement isn't nearly as important as discontinuous improvement. Creativity is a discontinuity. A creative act breaks with the chain that has come before it. It's not continuous. One cannot become a leader by continuously improving. That's imitation of the leader. You never overcome a leader by imitating them and improving slightly. You only become a leader by leapfrogging those who are ahead of you. And that comes about through creativity.
