One can have no smaller or greater mastery than mastery of oneself.

You will never have a greater or lesser dominion than that over yourself...the height of a man's success is gauged by his self-mastery; the depth of his failure by his self-abandonment. ...And this law is the expression of eternal justice. He who cannot establish dominion over himself will have no dominion over others.

Life is an art, and you are the artist.

A painter should begin every canvas with a wash of black, because all things in nature are dark except where exposed by the light.

Painting is poetry that is seen rather than felt, and poetry is painting that is felt rather than seen.

Art is never finished, only abandoned.
