|Robert Henri - The Art Spirit|
"The art student must master from the beginning; that is, he must be master of such as he has. By being now master of such as he has there is promise that he will be master in the future.
A work of art which inspires us comes from no quibbling or uncertain man. It is the manifest of a very positive nature in great enjoyment, and at the very moment the work was done.
It is not enough to have thought great things before doing the work. The brush stroke at the moment of contact carries inevitably the exact state of being of the artist at that exact moment into the work, and there it is, to be seen and read by those who can read such signs, and to be read later by the artist himself, with perhaps some surprise, as a revelation of himself." Robert Henri - The Art Spirit
People ... if you don't have this book I suggest you get it and read it again and again. I always use his writings to inspire me to a new season of paintings.
