Quote by Edward de Bono
Removing the faults in a stage-coach may produce a perfect stage-coach, but it is unlikely to produce the first motor car.
Summary
This quote suggests that trying to improve upon an existing concept or system may result in a refined version of that concept, but it is unlikely to lead to revolutionary innovations or advancements. Fixing the faults and shortcomings of a stage-coach, for example, may result in a perfected version of a stage-coach. However, it is unlikely to bring about a completely new and groundbreaking invention like the motor car. The quote highlights the need to think beyond incremental improvements and encourages thinking outside the box to create something truly transformative.
