You must renounce all superficiality, all convention, all vanity and delusion.

I am thrice homeless, as a native of Bohemia in Austria, as an Austrian among Germans, and as a Jew throughout the world. Everywhere an intruder, never welcomed.

It is easier to achieve a desired result in short pieces.

Don't bother to look, I've composed all this already.
