We may predict the future outcome based on our past experience. But how many have the foresight to know the future accurately? Anything can happen in the future. We can plan all that could be planned, the future outcome is still subjective.
Seizing the right moment is an important factor in ensuring we succeed or we fail. We may lack the foresight, but if we are aware and mindful of the rare opportunity that comes knocking our door, we will succeed. This opportunity is definitive and will produce the results that we want if we work on it. If we miss this opportunity, we may not get it again.
Buddhism taught us to live the present, to forget the past and to not worry about the future. Hence, i would say seizing the right moment is more important than having the foresight.
