Which is better, more promising and easier to succeed, learning Chinese painting and calligraphy or writing novels? I am 4 1 year old and have obsessive-compulsive disorder. Which one suits me better?

Of the three, novels are more successful, while China's paintings and calligraphy are more cultured. However, if you want to make money, I recommend you to write novels. Well written, the income is still very good, but don't worry. Few novels can become an instant hit. Novels have many themes, such as fantasy, romance, beauty, suspense and so on. If you want to write something, or it is more convenient, you can find that novel.
