1. Wrote a short story in Chinese yesterday and could not sleep after that. I decided to give it up. Literature is bad for my health...

2. Came across a book. A good textbook should be rigorous, concise and never short of intuition. This book is not good in the sense that it is not concise enough. But numerous examples and detailed explanations make it a good book to read before bed. Yes, I will read it instead of writing nonsense stories.
