A person hears only what they understand.

Every great idea exerts, on first appearing, a tyrannical influence: Hence, the advantages it brings are turned all too soon into disadvantages.

To hard necessity ones will and fancy must conform.

People who think honestly and deeply have a hostile attitude towards the public.

Plunge boldly into the thick of life, and seize it where you will, it is always interesting.

Deny yourself! You must deny yourself! That is the song that never ends.

Let no one be like another, yet everyone like the highest. How is this done? Be each one perfect in himself.
