"My theory is about moments.
Moments of impact.
My theory is that,
these moments of impact,
these flashes of high intensity
that completely turn our lives upside down
actually end up defining who we are.
The thing is,
each one of us is the sum
total of every moment
that we've ever experienced,
with all the people we've ever known.
It is these moments that become our history,
like our own personal greatest hits of memories
that we play and replay in our mind,
over and over again.
A moment of total, physical, mental,
and every other kind of love.
So that is my theory,
that these moments of impact
define who we are.
A moment of impact.
A moment of impact has potential for change,
has ripple effects far beyond
what we can predict.
Sending some particles crashing together
making them closer than before,
while sending others off into great ventures,
ending where you never thought you'd find them.
You see that's the best thing of moments like these,
no matter how hard you try,
control how they are going to affect you.
You just got to let the colliding particles
land where they may. And wait.
For the next collision."
