We seldom think of what we have but always of what we lack. Therefore, rather than grateful, we are bitter.
Arthur SchopenhauerIt is only a man's own fundamental thoughts that have truth and life in them. For it is these that he really and completely understands. To read the thoughts of others is like taking the remains of someone else's meal, like putting on the discarded clothes of a stranger.
Arthur SchopenhauerThus, the task is not so much to see what no one yet has seen, but to think what nobody yet has thought about that which everybody sees.
