Lee opens a dojo because he feels like he isn't keeping up with his training. He is hoping challengers will come to his dojo to face him in battle.
and have not been able to set aside
as much time for training as I’d like to.
.ولم أتمكن من إيجاد وقت كاف للتدريب كما أريد
dass ich nicht so viel Zeit zum Trainieren
aufbringen konnte, wie ich wollte.
che non ho avuto più tempo
 per allenarmi come ero solito.
E não tenho conseguido
treinar tanto quanto gostaria.
