"Sapere aude! Dare to know! Have the courage to use your own understanding."

"Two things awe me most: the starry sky above and the moral law within."

"I am never content with myself in relation to my knowledge and virtue."

"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"
