I am going to have a 3-week trip in China. Now, I plan to choose a book and bring it with me
along the whole trip. I hope the book is small but insightful. The book could provide me a way to rethink and reflect what I am really interested in. The book could guide me in my life. What kind of book should I bring?

I have several candidates:

1. D. Knuth's "Selected Paper on Computer Science"
2. Christopher Alexander's "The Timeless Way of Building"
3. Donald Norman's "The Design of Everyday Things"

I am looking for a metapher, a paradigm, a way of thinking which can prfoundly reshape me.
