Chance created the situation; genius made use of it. - Leo Tolstoy

I do value my work awfully; but in reality only consider this: all this world of ours is nothing but a speck of mildew, which has grown up on a tiny planet. And for us to suppose we can have something great - ideas, work - it's all dust and ashes.

Here's my advice to you: don't marry until you can tell yourself that you've done all you could, and until you've stopped loving the women you've chosen, until you see her clearly, otherwise you'll be cruelly and irremediably mistaken. Marry when you're old and good for nothing...Otherwise all that's good and lofty in you will be lost.

My principal sin is doubt. I doubt everything, and am in doubt most of the time.
