Theodor Fontane

The most beautiful thing in life is that our souls remain hovering over the places where we once enjoyed ourselves.

Error is also fine, as long as we don't stay in it.

To do what you love — that is freedom.

The secret of life is to take the good things when they come.

Only he who knows his weakness will ever become strong.

Old age is only bearable if one has not lost the desire to become young again.
