until he finished his homework。 And had to read two books a week, and write book reports about them。 His mother’s strategy worked。 “Of course, I didn’t know she couldn’t read。 So there I was

submitting these reports。” he said。 She would put check marks on them like she had been reading them。 As I began to read about scientists,economists and philosophers。 I started imaging myself in their shoes。 As he got into the hobbit of hard work, his grade began to soar。 Ultimately he received a scholarship to attending Yale

University, and later he was admitted to the University of Michigan Medical School。

He is now a leading surgeon at Johns Hopkins Medical School and he is also the author of the three books。
