“Anything that lights your world leaves it dark once it's gone.”

“You're alive...That means you have infinite potential. You can do anything, make anything, dream anything. If you change the world, the world will change. Potential. Once you're dead, it's gone. Over. You've made what you've made, dreamed your dream, written your name.”

“The greatest thing you will ever give to the world is your committment to leave what you find in better condition than the way you found it. Leave a single light in a place where there was once darkness so those coming behind you may see further and begin where you left.”

“You're alive, Bod. That means you have infinite potential. You can do anything, make anything, dream anything. If you can change the world, the world will change. Potential. Once you're dead, it's gone. Over. You've made what you've made, dreamed your dream, written your name. You may be buried here, you may even walk. But that potential is finished.”

“Light is shallow; darkness is infinitely deep. Light is always bounded, it has boundaries. Darkness has no boundaries, it is unbounded. Light comes and goes; darkness always is. When there is light you cannot see it. When light is not there you can see it. But it is always there; you cannot cause it. Light has a cause. You burn the fire, you put on wood. When the wood is finished the light will be gone. It is caused, hence it is an effect. But darkness is not caused by anything, it is not an effect. It is uncaused eternity.”

“I mean, creatures who only exist in the dark don't know they're missing the sun, right? But once you've seen the sun. Once you've seen it light up the world ... once you've felt its heat all around you ... inside you ..." He clutched his own chest, and my heart cracked open. "Its hard to live in the dark after the sun dies.”
