Something about standing on the lip of that great expanse called "Tomorrow" makes a person want to take stock of his or her life and see where they've been, look at what direction they're heading, and dream of what could be.
"Tomorrow" is a limited resource, though...as the following video by zefrank1 makes abundantly clear.
Truth is...none of us has a guaranteed number of beans. May each one we are granted be spent in a way that is true, noble, right, pure, lovely, admirable, excellent, and praiseworthy. (Philippians 4:8)
