How many years you have to keep on doing until you know what to do and how to do!

What's foreign one can't always keep quite clear of,For good things, oft, are not so near;A German can't endure the French to see or hear of,Yet drinks their wines with hearty cheer.

Du hast so viele Leben, wie du Sprachen sprichst. (You have as many lives as the number of languages you speak.).

On all the peaks lies peace.

Anything in the world can be endured, except a series of wonderful days.

Each one sees what he carries in his heart.
