Ahh yes, i remember that moment when i helped someone realize that the moment was just a little fragment of one's life, and that once you realize you have a future it is an amazing thing. Your whole perspective on life changes, and your past is full of why....
When you realize that What If, and see that there is so much more to life than today, and you are constantly building for tomorrow, because when that person realizes that tomorrow is promised. It is a beautiful thing, and only leads to further happiness, and the only thing holding them back.... well their past and themselves.
