いわゆるノウハウ本です。
さまざまなノウハウを一冊に詰め込んだため、各論の内容は薄いかと思います。
ただ、何に気をつければいいかはよくわかりました。
実践に移すには他の本も参考にした方が良いかもしれないと感じました。
This book is so called a 'know how' book.
It covers quite a wide range of tips and points to be checked when you talk in public.
However, the range was too broad to look into the details.
Therefore, you may have to refer to other related books if you step in a practical action.
Having said that, the book is quite useful in the sense that you can see what you should be careful of when talking in general.
