Invictus

I am the master of my fate: I am the captain of my soul.
我是我命運的主人：我是我靈魂的船長。 - Nelson Mandela

While incarcerated on Robben Island prison, Nelson Mandela recited the poem to other prisoners and was empowered by its message of self mastery.
In the movie Invictus, Mandela gives the captain of the national South African rugby team the poem to inspire him to lead his team to a Rugby World Cup win, telling him how it inspired him in prison.
