“If on your own or by the criticism of others you discover error in your work, correct it then and there; otherwise, in exposing your work to the public, you will expose your error also. Don’t make excuses, persuading yourself that you will retrieve your reputation in some future work, because your work does not fade when it leaves your hands like the sound of music, but remains a standing monument to your ignorance. If you protest that you have not time to take pains necessary to be a great painter, having your living to make, you have only yourself to blame: for the study of what is excellent is food for mind and body.
A philosopher born to great riches will give them all away rather than be deflected for a moment from his true pursuit.”
