I don't have one inspiration, I don't really believe in having a single main source of inspiration. I get inspired from everyday people who I meet and read about, true everyday heroes. Such as the American Jewish farmer who lived his entire life in a very meager state and then donated 15 million dollars close to his death to help build up agriculture in the Negev. I get different inspirations from different types of people and then combine them together which gives me an idea of the type of person I should strive to be.
My father and grandmother were always big inspirations to me though.
