The good news about a self portrait is that you are your own model and will pose all day long, if you want. The bad news is that the model is you. The good news is that you don't have to pay yourself. The bad news is that you have to look at yourself all day long - and you don't get paid for doing it. The good news is that as years go by, there are more and more "landmarks" in your face to work from. The bad news is that those "landmarks" are actually wrinkles. But I will end with a surprising piece of good news: to be honest, it is a lot more interesting to paint an older face than a younger one. So there you go.
