"The hardest thing is living with yourself when you know what you've done."

"I know what it's like to have power forced upon you. It's not freedom."

"Everyone I've ever cared about has left. But I keep moving forward."

"Gratitude makes life richer."

"A grateful heart is a happy heart."

"Respect those who came before us."

"Life's greatest treasures are the people we love"
