heroic underdog

What we all admire and respect is the person who stand up against overwhelming difficulties and persevere(vi) without a promised outcome.
Michael "Eddie" 愛德華, nicknamed "Eddie the Eagle" by the media, is a British ski jumper and skier who represents Great Britain in 1929 Olympic ski jumping.
To realise his Olympic dream, despite of the fact he is short of funds, Eddie used second-hand equipment. He had to wear six pairs of socks to make the boots fit.
