Its not a moive but a 10 part docu-series on the life of Michael Jordan and his Basket ball team The Chicago Bulls. Its called "The Last Dance". If you want motivation and true motivation, I highly recommend watch "The Last Dance".
Sports movies are what motivated me. Theres a sense of achievement, a feeling of striving for greatness and the agrression in doing so, it tends to rub off on you, even if your watching a sports related movie.
