Quote by Kant, Immanuel

"Act only according to that maxim whereby you can at the same time will that it should become a universal law."

"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."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
