Man is unhappy because he doesn't know he's happy. If anyone finds out he'll become happy at once.
Fyodor DostoevskyA true friend of mankind whose heart has but once quivered in compassion over the sufferings of the people, will understand and forgive all the impassable alluvial filth in which they are submerged, and will be able to discover the diamonds in the filth.
Fyodor Dostoevsky
