Why do we keep pushing our skills, our education? What happened to the person who was content to just have a job and a home? Why, as an artist; should we still keep trying to learn new things? Is it a problem that we never seem to be content? I don't think so.
The longer we live, the harder it is to consider going back to the beginning. Just like getting good at failing, you can be good at starting over; they both go hand in hand.
