Dušan Krtolica is a gifted artist. I hope he is encouraged to explore other experiences in life besides drawing. The article says he does on average 500 drawings a week. No matter how creative and talented he may be, I'd worry that this little boy was becoming compulsive and obsessive about one thing. He can still enjoy a long life as a renowned artist, but he will be a much healthier person emotionally, as he matures, if he's encouraged to play more and enjoy his childhood.
