Hey Sri, when we look back to events in the past, we can see how they eventually turned out, which is a benefit that we did not have at the time. This is known as benefit of hindsight.
the dictionary meaning is " the ability to understand, after something has happened, what should have been done or what caused the event "
I was really confused back then about the decision I needed to take. Now with the benefit of hindsight, it is so easy to choose. Wish we had this benefit back then, things could never go wrong.
