This experience motivated me to continue my work on the heart and circulation. Later, after a year of internship at the Presbyterian Hospital in New York city, I continued my training in renal and cardiac physiology, amongst them at New York University and Bellevue Hospital. Later I accepted a position as an assistant professor in medicine at the Johns Hopkins Hospital working in the field of hypertension. After serving in the US Army Medical Corp, I returned to Hopkins where I was part of the team interested in surgical correction of children with congenital heart disease. This was the final experience which directed my career toward investigation and treatment of heart disease.
Creativity is an inborn characteristic.
It however amounts to little if the urge does not result in tangible creation. One cannot turn on creativity as one would turn on a faucet. The creative drive is genetically determined and enforced by education. Self discipline is important. In order to be creative, one has to be programmed genetically and one has to have the willpower, the strength, and the endurance to convert the creative process into tangible creative works.
