The notes I am taking on in my notebook is about a book called “Quiet Power” written by Susan Cain. The main topic about this book is “Introverts”. Introverts are people who are often quiet and does not express their thinkings and voices often. But the authors opinion in this book is introverts can also be very powerful and strong leaders without being very talkative. Introverts should also be proud of their personalities and find a comfortable way they like to express. Many people think introverts are not very powerful because they do not have the technique to express and share. The author proves in this book that introverts are not weak at may master other techniques way more than other people.
