When you look back at something that happened in the past, it is much easier to see how something could have been prevented or done differently… especially, when you have more of the facts AFTER the event. That’s called hindsight.
When you have the ability to predict what will happen or be needed in the future, it is easy make wise decisions. That’s called foresight.
A great quote that speaks to both says:
Hindsight explains the injury that foresight would have prevented.
