In the spring of 1871, a young man picked up a book and read 21 words that changed his life.
At the time, this man was a medical student at Montreal General Hospital.
He was worried about final examinations. He was troubled about what he should do with his life, where he should set up his medical practice and how he would build it.
The 21 words that changed his life were written by Thomas Carlyle. The man who was worried was William Osler, founder of Johns Hopkins School of Medicine in Maryland.
