What makes one day important in the grand scheme of life?

Ok, so this question was asked to me by a teacher. I have been thinking of an answer and here's what I've got: To me this means that everyday should count. Seeing that everyday is a gift. You never know when your life will end so why not make everyday count? By that I mean love like you've never loved before, forgive like there's no tomorrow, and look at things like you've never looked at them before. If someone says they are truely sorry than forgive and forget. If someone's not loveable love tham no matter what anyone else says or does about it. Just look at people and things to a point that there's no other way to look at it! Have an open mind:)
