(Nowadays, the word of Yozan UESUGI, the lord of the Yonezawa domain, `If you try to do, it can be achieved, if you don't, it will never be achieved. Achieving nothing is due to one's own intention to not try.' is better known than the word of Shingen, but was originally a quote from Shingen).
（現在では米沢藩主・上杉鷹山の言葉としての「為せば成る為さねば成らぬ何事も成らぬは人の為さぬなりけり」の方が良く知られているが元々は信玄の言葉である）
