To do a drawing for a painting most often means doing something very sketchy and schematic and then later making it polished.

I'm working in my mind.

I'm not sure what 'coming out right' means. It often means that what you do holds a kind of energy that you wouldn't just put there, that comes about through grace of some sort.

I often find that having an idea in my head prevents me from doing something else. Working is therefore a way of getting rid of an idea.

One works without thinking how to work.

There was very little art in my childhood. I was raised in South Carolina; I wasn't aware of any art in South Carolina. There was a minor museum in Charleston, which had nothing of interest in it. It showed local artists, paintings of birds.

Take an object. Do something to it. Do something else to it.
