Politically Incorrect Old Classic
That modern icon, Forrest Gump, was intellectually challenged, but nevertheless worked very hard to maximize his potential, such as it was. The protagonist of this story, Rosemary, was very similar to Forrest in many respects. She worked very hard, she studied hard, and she greatly hated being less smart than the other children. Generally, this made her work even harder, but at times she became discouraged. One day she asked her favorite teacher if she really would someday become smarter if she continued to work very hard. The encouragement came, "You will be partially sage, Rosemary, in time."
