Do not try to live forever. You will not succeed.

My religious convictions and scientific views cannot at present be more specifically defined than as those of a believer in creative revolution. I desire that no public monument or work of art or inscription or sermon or ritual service commemorating me shall suggest that I accepted the tenets peculiar to any established church or denomination nor take the form of a cross or any other instrument of torture or symbol of blood sacrifice.

Beware of the man who does not return your blow: he neither forgives you nor allows you to forgive yourself.

He knows nothing and thinks he knows everything. That points clearly to a political career.

Don't order any black things. Rejoice in his memory; and be radiant: leave grief to the children. Wear violet and purple. Be patient with the poor people who will snivel: they don't know; and they think they will live for ever, which makes death a division instead of a bond.

I want to be thoroughly used up when I die, for the harder I work the more I live. I rejoice in life for its own sake.

All progress depends upon the unreasonable person.
