"He who looks in the crystal ball ends up eating glass... They're way, way close"

This quote by Mary Matalin is a caution against relying too greatly on predictions and forecasts. It suggests that when we try to anticipate the future, we typically get it incorrect and end up dissatisfied. The phrase "eating glass" is a metaphor for the pain and suffering that can originate from being incorrect. Matalin is saying that predictions and forecasts are often close, but not close enough to be reliable. She is alerting us to be careful when counting on forecasts and forecasts, as they can often lead to dissatisfaction and pain. The quote is a pointer to be conscious of our expectations and to be prepared for the unexpected. It is a pointer to be versatile and available to change, as the future is frequently unforeseeable.
