Why settle for "good" when "great" is available? No substitute for hard training!
Gusukuma believed growth only came through ii nangi- extreme effort/striving. He lost the fingernails on both hands from bamboo nukite conditioning, developed immense jumping and swinging abilities through acrobatics, and could punch many times his body weight from makiwara striking. A no-nonsense teacher, he was quick to dismiss students who lacked effort and always expected exertion to the point of exhaustion in kata's repetition once the basic form was learned. Iha Sensei said that if you were not spent after doing a kata Gusukuma would ask why you didn't try harder.
