Some of the greatest inventors, artists and minds of our time have died alone and penniless.
example;
Vincent Van Gogh-
Today his iconic paintings sell for tens of millions of dollars each and his style is immediately recognizable to people all over the world. But in his lifetime, van Gogh made only $109 from sales of his paintings. He was a troubled artist who struggled with anxiety and mental illness most of his life, which was not helped by his inability to find appreciation for his work. Cutting off his earlobe in December 1888 was the start of his last downward spiral that culminated with van Gogh (presumably) shooting himself in the chest. His last words were, "The sadness will last forever."
