where there is a will, there is a way

With the saying 'Where there is a will, there is a way' in his heart, he overcame the great challenge.
A classical Japanese proverb of Chinese origin, combining 精神一到 (concentration of mind) with 何事か成らざらん (what cannot be accomplished?). The exact historical derivation is uncertain.
