I rediscovered the excerpt I previously talked about from the book, "Letters to a Young Artist."
The real life of the artist is solitary.
The central fact of artists' lives - the part that non-artists never seem to quite understand - is the loneliness of the studio. Before our runs are over we will have spent more time - thousands upon thousands of hours - alone, just staring at these things we make. This part of our experience must be factored in to every idea about artis' lives if you want to understand them. More artists stop working because of this loneliness than for any other reason.
If there is one essential survival skil that you must learn, it is how to sustain yourself and your work over the years. There is really only one way to do this, and that is by loving what you do, being fascinated by your work, and by being obsessed with making art. You will get in trouble if you need approval of others to keep your work moving forward. After all these years, the one essential element in my practice, the one thing I am sure of is what I need to be interested in and happy about what I am doing in the studio.
