I'm gaining confidence sketching because I started this portrait at work. Hey, wait a minute. Don't you work at that convenience store with the constant parade of people? Yep, I do but I worked on it in 3 to 60 second intervals. I had 90% of it done by the time I closed the store. One of the most important things I've learned as an artist and writer is to work whenever and wherever you can. You can't always wait for a free schedule....Maybe tomorrow I'll set up an easel and take my paints.
