Take a look at the sketch above. Ask yourself if the artist is talented, or untalented, and try to articulate your reasons.
Does your opinion of the talent possessed by this artist change when I tell you that the artist was 27 years old when he made the sketch? If a 27 year old man came to you, handed you this sketch, and told you he intended to pursue art as the primary focus of his life, what would your advice be?
Would you tell him to give it up, get a decent paying job, find a wife and have some kids, and forget about the whole art thing?
Or would you tell him "This sketch seems pretty primitive, I know. But it's important not to judge your abilities as an artist based on what you're doing now. Go work hard, and see where you end up."
Does your opinion change if I tell you that 5 years after making that sketch, the artist painted this, and then two years later this, and then a year later this?
