This adaptive approach acknowledges the unpredictability of the future and allows for flexibility in decision-making, mitigating the potential consequences of inaccurate forecasts.

In conclusion, Edgar Fiedler's quote "He who lives by the crystal ball soon learns to eat ground glass" serves as a powerful reminder of the risks and limitations associated with relying too heavily on predictions and forecasts. It encourages a cautious and adaptable approach to decision-making, emphasizing the need to recognize the inherent uncertainty of the future.
