It is important that you hold to a high standard. To achieve this I suggest you paint your pictures for a person you hold in your mind. A person you admire and someone you would like to approve of your work. You must never tell this person of the commitment you have made.
To be accepted into the world of art you must embrace the politics of the art world. Part time work with a city gallery or regional gallery is always helpful. Rest assured ,that if you ignore the politics of the art world, the art world will ignore you.
