Grandads words

Yesterday is a canceled check.
Tomorrow is a promisorry note.
Only today is negotiable cash.
Spend it wisely!

Something I found that my grandfather had jotted down in his bible. I am not sure where he got the quote from. Maybe it was something the preacher had said during a sermon.... I did not receive the bible until after he had passed years ago so I guess i will never know the source.
