It had long since come to my attention that people of accomplishment rarely sat back and let things happen to them. They went out and happened to things.

I love those who can smile in trouble.

Those who fall in love with practice without science are like a sailor who enters a ship without a helm or a compass, and who never can be certain whither he is going.

For those colours which you wish to be beautiful, always first prepare a pure white ground.

Just as a well-filled day brings blessed sleep, so a well-employed life brings a blessed death.

Whoever does not respect life, does not deserve it.

If you are alone you belong entirely to yourself. If you are accompanied by even one companion you belong only half to yourself or even less in proportion to the thoughtlessness of his conduct and if you have more than one companion you will fall more deeply into the same plight.
