おしゃべりな筋肉

[DeepL Translation - needs review] Takanori Nishikawa = Positive, cheerful and sociable?　I used to be negative, shy, and workaholic, but I finally got to this point by accumulating training both mentally and physically - 20 years after debuting as T.M.Revolution. In this book, I write about seven ways to train your mind that you can start today, based on the experiences I have learned through many failures.
