12. George Soros
George Soros is a testament to perseverance and determination. He grew up as a non-observant Jew in Hungary and was 13 when the Nazi’s invaded. He eventually went into hiding and then emigrated to England in 1947. He worked as a railway worker and a waiter in order to put himself through school. It was through working a wide range of jobs that he realized none of it was right for him. So he wrote letters to every merchant bank in London until one of them gave him a job. He moved through the ranks to become one of the most successful hedge fund managers in history with a net worth of over $20 billion.
