Leo Tolstoy said this quote

They say: misfortunes, sufferings...well, if someone said to me right now, this minute: do you want to remain the way you were before captivity, or live through it all over again? For God's sake, captivity again and horsemeat! Once we're thrown off our habitual paths, we think all is lost; but it's only here that the new and the good begins. As long as there's life, there's happiness. There's much, much still to come.
