Looking back you realize that a very special person passed briefly through your life- and it was you. It is not too late to find that person again.
The moment you feel you have to start proving your worth is the moment you should walk away and never look back.
Enjoy the time you have now, live in this moment and never look back. Whatever happens, happens. Don't stress.
I always knew looking back on my tears would bring me laughter, but I never knew looking back on my laughter would make me cry.
