Anton Chekhov said this quote

Ivanov: With a heavy head, with a slothful spirit, exhausted, overstretched, broken, without faith, without love, without a goal, I roam like a shadow among men and I don't know who I am, why I'm alive, what I want. And I now think that love is nonsense, that embraces are cloying, that there's no sense in work, that song and passionate speeches are vulgar and outmoded. And everywhere I take with me depression, chill boredom, dissatisfaction, revulsion from life... I am destroyed, irretrievably!
