1. You can finish the book in 45 minutes, if not less. 2. It will give you lot of ways to fuel your creativity. You can be in any field. 3. It is a bit preachy at the end. 4. The book looks too small for the price you pay for it. I mean I bought it for Rs. 535 and finished it in 45 minutes.
Overall, recommended reading. A lot of stuff has appealed to me. Since it is a very small book, you can buy an e-version and save money.
