Iapply mo . yun yung pinaka the best na sagot! :) applying it doesnt mean that you are going to to do it again. for example, yung mga pagkakamali mo .. maiiwasan mo ng gawin ulit if ever na mangyayari ulit yun. (well, history repeats itself) . yung ganun.
In short gawin mong guide yung past para sa present.
