Rafał Grzesiakowski

“Marry, and you will regret it; don’t marry, you will also regret it; marry or don’t marry, you will regret it either way. Laugh at the world’s foolishness, you will regret it; weep over it, you will regret that too; laugh at the world’s foolishness or weep over it, you will regret both. Believe a woman, you will regret it; believe her not, you will also regret it… Hang yourself, you will regret it; do not hang yourself, and you will regret that too; hang yourself or don’t hang yourself, you’ll regret it either way; whether you hang yourself or do not hang yourself, you will regret both. This, gentlemen, is the essence of all philosophy.”
― Søren Kierkegaard

“Physics is like sex: sure, it may give some practical results, but that's not why we do it.”
― Richard P. Feynman

“When I write, I feel like an armless, legless man with a crayon in his mouth.”
― Kurt Vonnegut

“The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.”
― Ralph Waldo Emerson
