Go to foreign countries and you will get to know the good things one possesses at home.

Even dirt glitters when the sun is shining upon it

A man would create another man if one did not already exist, but a woman might live an eternity without even thinking of reproducing her own sex.

To become aware in time when young of the advantages of age; to maintain the advantages of youth in old age: both are pure fortune.

No one can take from us the joy of the first becoming aware of something, the so-called discovery. But if we also demand the honor, it can be utterly spoiled for us, for we are usually not the first. What does discovery mean, and who can say that he has discovered this or that? After all it's pure idiocy to brag about priority; for it's simply unconscious conceit, not to admit frankly that one is a plagiarist.

So long as you live and work, you will be misunderstood; to that you must resign yourself once and for all. Be silent!

Life belongs to the living, and he who lives must be prepared for changes.
