We're all familiar with that Picasso quote about it taking a lifetime to learn to draw like a child. That's 'cause kids don't agonize over talent, impressing others, failure, success, or any of the other mental pitfalls that plague adults. They just sit down and paint.
Here are two portraits I made of my parents when I was 4. I distinctly remember deciding I was going to do this, asking them to pose for me (which they kindly consented to), and then just sitting down and drawing. It never occurred to me that the drawings might not turn out well; I never wondered whether I was using the right colors, or whether something looked right or wrong. I just decided to do it, and I sat down and did it. And what fun I had!
