This book makes me realize the importance of output. As the most book lovers already know, just reading books is not enough if you truly want to master the skills or the mindsets that you learned the books you read. Doing output is indispensable. Many people, including me, tend to stand ready when it comes to output something. This book teaches me that I can start output in the way I like. The way of output is not necessarily sophisticated and you don't have to be stick to the form. What is the matter is continue output. I will keep in mind what I've learned form this book and put it into practice.
