A Moment

Theres a moment where everything flashes before your eyes, and every part of your being cries out. 
You see all that was, and you wounder about all that will ever be. 
You come to question who you are. Is this who your truly meant to be? 
Taking a look in the mirror years of experience is what you see. Someone worn with many battle scars is reflected back at you.Yet beauty can still be found. 
As you stand there you seem broken, defeated, scars running deeper than anyone will ever know.
Yet there is this power, a power that's kept you standing, kept you going, and keeps you fighting all this time 
What is this power? Is there even a word to define it.
Raking your brain for an answer none comes to mind. Maybe before long the answer will come.
