Summary
This quote suggests that critics often arrive after the fact, voicing their judgment or opinions when it is already too late for any changes or improvements to be made. It implies that critics tend to be reactionary rather than proactive, appearing only once a particular situation, decision, or action has been completed. The quote serves as a reminder that criticism is more valuable when shared beforehand, allowing for a possibility of positive change or growth, rather than being offered solely as a retrospective critique.
