Sidney Poitier
When Sidney Poitier first moved to New York from the Bahamas with just three dollars, he struggled to find acting roles due to his accent. He worked as a dishwasher and, at times, was homeless, sleeping in public bathroom stalls. Determined, Poitier bought a radio and spent hours mimicking the hosts to perfect his speech.
His perseverance paid off, as he became a trailblazer for people of color in Hollywood, and at the time of his passing, Poitier's net worth was $20 million.
